BANDSTRA, C.J.

Defendant appeals as of right from his conviction in a jury trial of two counts of delivery of methadone in an amount less than fifty grams, MCL 333.7401(2)(a)(iv); MSA 14.15(7401)(2)(a)(iv), and one count of delivery of heroin in an amount less than fifty grams, MCL 333.7401(2)(a)(iv); MSA 14.15(7401)(2)(a)(iv). We affirm.

This case arises out of several undercover drug sales that occurred in April, May, and June 1997. A recovering heroin addict working with the Southwest Enforcement Team, an undercover narcotics unit, testified as the prosecution's chief witness that he purchased methadone and heroin from defendant on various occasions.

Defendant argues that the court erred in sustaining the prosecutor's challenge of a venireman for cause on the basis that the venireperson was biased against the use of a paid informant. We review for abuse of discretion a trial court's rulings on challenges for cause based on bias. People v Roupe, 150 Mich. App. 469, 474; 389 N.W.2d 449 (1986). MCR 2.511(D)(3), (4), and (5) provide in pertinent part that a venireman may be excused for cause based on a demonstrated bias for or against a party, if the venireman shows a state of mind that will prevent the juror from rendering a just verdict, or if the venireman has opinions that would improperly influence the juror's verdict.

Defendant argues that the venireman exhibited mere skepticism rather than bias against the paid informant witness, and that such skepticism did not constitute cause for purposes of dismissal. We disagree. The venireman unequivocally stated that he would not be able to find defendant guilty on the basis of a paid informant's testimony. This Court defers to the trial court's superior ability to assess from a venireman's demeanor whether the person would be impartial. Butler v DAIIE, 121 Mich. App. 727, 746; 329 N.W.2d 781 (1982). The court did not abuse its discretion by excusing the venireman for cause.

Next, defendant argues that the court violated his due process rights by impaneling an "anonymous jury." We disagree. The court's decision to refer to jurors by number rather than name is a decision concerning the conduct of voir dire, which we will review for abuse of discretion. See People v Daniels, 192 Mich. App. 658, 666; 482 N.W.2d 176 (1991).

An "anonymous jury" is one in which certain information is withheld from the parties, presumably for the safety of the jurors or to prevent harassment by the public. Anno: Propriety of using anonymous juries in state criminal cases, 60 ALR5th 39, § 2[a], p 47. The withholding of information from parties was first used in federal courts, primarily as a protection against dangerous individuals. See United States v Barnes, 604 F.2d 121, 140-141 (CA 2, 1979). Use of this procedure in state courts began in the past decade. 60 ALR5th 39, supra. The courts have recognized that the use of an "anonymous jury" may promote the safety of prospective jurors, but at a potential expense to two interests of the defendant: (1) the defendant's interest in being able to conduct a meaningful examination of the jury and (2) the defendant's interest in maintaining the presumption of innocence. 60 ALR5th 39, § 4, pp 52-54; see also anno: Propriety of, and procedure for, ordering names and identities of jurors to be withheld from accused in federal criminal trial — "anonymous juries," 93 ALR Fed 135, § 2[a], p 139. In order to successfully challenge the use of an "anonymous jury," the record must reflect that the parties have had information withheld from them, thus preventing meaningful voir dire, or that the presumption of innocence has been compromised. See, e.g., People v Phillips, 56 Cal.App.4th 1307, 1310; 66 Cal.Rptr.2d 380 (1997); State v Bowles, 530 N.W.2d 521, 529-530 (Minn, 1995).

The record in the present case does not support the conclusion that an "anonymous jury," in the strict sense of the term, was impaneled. As previously mentioned, the practice of impaneling an "anonymous jury" is an extreme measure, in which "certain biographical information about potential jurors" is withheld, even from the parties. United States v Branch, 91 F.3d 699, 723 (CA 5, 1996). By contrast, in this case, jurors were merely referred to at trial by number rather than by name. There is nothing in the record to support the conclusion that any information was actually withheld from the parties. At most, the names of the jurors were replaced by numbers. Just as in Branch, "[t]he jurors here were not `anonymous' except in the most literal sense"; that is, their names were not read into the record. Id.

Defendant admitted on the record that he had access to the jurors' biographical information, as contained in the juror questionnaires. See MCR 2.510. Furthermore, the voir dire conducted by both parties demonstrates that that information was not withheld from the parties. There is nothing to indicate that defendant's ability to effectively examine the venire was compromised in any way.

In addition, there is nothing in the record to indicate that the use of numbers undermined the presumption of innocence. There is no suggestion that jurors understood the use of numbers rather than names to be anything out of the ordinary. Thus, there was no suggestion that defendant's trial was being handled in a special way, with the resulting implication that he was generally dangerous or guilty as charged. Other state appellate courts have declined to review claims of prejudice in the withholding of jurors' names in the absence of any evidence in the record of prejudice. For instance, in Bowles, supra at 529-530, the Minnesota Supreme Court discussed the issue of prejudice:

Like the presence of uniformed and armed security personnel at trial that was at issue in Holbrook [ v Flynn, 475 U.S. 560; 106 S.Ct. 1340; 89 L.Ed.2d 525 (1986)], the use of an anonymous jury "need not be interpreted [by jurors] as a sign that [the defendant] is particularly dangerous or culpable." 475 U.S. at 569; 106 S.Ct. at 1346. Rather, jurors are as likely to conclude their anonymity is designed to protect them from media or public pressures. Indeed, jurors who are unaware that anonymity is unusual are likely to draw no conclusions at all from the practice. We conclude that the use of an anonymous jury is not an inherently prejudicial practice.

Similarly, we see no reason to presume prejudice from the trial court's actions here.

We conclude that, under the facts of this case, defendant's due process rights were not violated by using juror numbers instead of names at trial. However, we caution the trial courts about the potential for prejudice arising from the use of anonymous juries. The procedure should be employed only when jurors' safety or freedom from undue harassment is, in fact, an issue, and, when used, appropriate safeguards should be carefully followed to assure a fair trial.

Finally, defendant argues that he was denied the right to an impartial jury drawn from a fair cross section of the community. We disagree. "Questions of systematic exclusion of minorities from venires are reviewed de novo by this Court." People v Hubbard (After Remand), 217 Mich. App. 459, 472; 552 N.W.2d 493 (1996). To determine whether a prima facie violation of the fair-cross-section requirement of US Const, Am VI has occurred, the court must find the following: (1) the group alleged to be excluded must be a distinctive group in the community; (2) the representation of this group in venires from which juries are selected is not fair and reasonable in relation to the number of such persons in the community; and (3) the underrepresentation is due to systematic exclusion of the group in the jury-selection process. Duren v Missouri, 439 U.S. 357, 364; 99 S.Ct. 664; 58 L.Ed.2d 579 (1979); Hubbard, supra at 473.

Defendant satisfies the first prong of the Duren/Hubbard test. "African-Americans are considered a constitutionally cognizable group for Sixth Amendment fair-cross-section purposes." Hubbard, supra at 473. However, neither the second nor third prong is satisfied. "[T]he second prong is satisfied where it has been shown that a distinctive group is substantially underrepresented in the jury pool." Id. at 474. However, like the defendant in People v Howard, 226 Mich. App. 528, 533; 575 N.W.2d 16 (1997), this defendant asserts that African-Americans were underrepresented in his particular array, but presents no evidence on jury venires in general. "Merely showing one case of alleged underrepresentation does not rise to a `general' underrepresentation that is required for establishing a prima facie case." Id.

Even if defendant had satisfied the second prong of the test, he has clearly failed to satisfy the third prong, which requires him to show that any underrepresentation is due to systematic exclusion. Hubbard, supra at 481. Defendant simply argues that "this prong will be met if a hearing is held on remand," and points out that "of the 50 prospective jurors, only two were African-American," while "nine percent of Kalamazoo County is African-American." "[I]t is well settled that systematic exclusion cannot be shown by one or two incidents of a particular venire being disproportionate." People v Flowers, 222 Mich. App. 732, 737; 565 N.W.2d 12 (1997). Furthermore, "[w]hile a criminal defendant is entitled to an impartial jury drawn from a fair cross section of the community, he is not entitled to a petit jury that exactly mirrors the community," and a "bald assertion" that systematic exclusion must have occurred is insufficient to make out a claim of systematic exclusion. Id. at 736-737. Defendant has the burden of demonstrating a problem inherent within the selection process that results in systematic exclusion. Defendant has failed to do so.

Defendant makes an alternative Fourteenth Amendment equal protection argument, claiming that he has shown a prima facie case of discrimination against African-Americans. Defendant cites Jefferson v Morgan, 962 F.2d 1185 (CA 6, 1992), and Alston v Manson, 791 F.2d 255 (CA 2, 1986), two cases challenging the composition of state grand juries, in support of his contention. To make out a case for systematic discrimination, a claimant must (1) show that the group excluded is a recognizable, distinct class capable of being singled out for different treatment under the laws, (2) prove the degree of underrepresentation by comparing the proportion of the excluded group in the total population to the proportion actually called to serve on the venire over a significant period, and (3) show that the selection procedure is either susceptible of abuse or not racially neutral. Castenada v Partida, 430 U.S. 482, 494; 97 S.Ct. 1272; 51 L.Ed.2d 498 (1977). Just as with defendant's Sixth Amendment claim, defendant has failed to make out a prima facie case under the Fourteenth Amendment. Defendant failed to show either that the system for selecting veniremen was subject to abuse or that his racial group was underrepresented over a significant period.

We affirm.
