OPINION

J. CURTISS BROWN, Chief Justice.

Appellant entered a plea of not guilty before the jury to the offense of aggravated sexual assault. See generally Tex.Penal Code Ann. § 22.021 (Vernon 1989). Appellant was convicted and the jury assessed punishment at confinement in the Institutional Division of the Texas Department of Criminal Justice for life and a fine of $10,000. In twelve points of error, appellant complains of the sufficiency of the evidence, prosecutorial misconduct, the trial court’s charges to the jury, unnecessarily suggestive pretrial identifications, the admission of DNA testing evidence, and the limitation of his voir dire examination. We affirm.

On January 16, 1988, the complainant was beaten and sexually assaulted in her home. During the course of the assault, the attacker held a knife to the complainant’s throat and threatened to kill her. The complainant, who was seventy four years old at the time of the attack, was able to observe her attacker for a period of about two hours. The complainant was sexually assaulted orally, anally and vaginally. The complainant identified the appellant from a police photo spread. After appellant’s arrest, the complainant identified the appellant in a police lineup. A DNA analysis was performed on a semen specimen the attacker left on the complainant’s mattress. The analysis produced an identical match with DNA obtained from appellant’s blood. At trial, the complainant positively identified the appellant as her attacker.

Appellant’s first and fifth points of error assert that the trial court erred in admitting the DNA analysis evidence at trial. Relying upon Frye v. United States, 293 F. 1013 (D.C.Cir.1923), appellant filed a pretrial motion to suppress the DNA fingerprint evidence on the ground that the evidence was the product of a novel and unreliable scientific test which has not gained general acceptance in the scientific community. During trial, a Frye hearing was held outside the presence of the jury regarding the admissibility of the DNA fin *225 gerprint evidence. At the conclusion of that hearing, the trial court ruled that the DNA fingerprint evidence was admissible under both the Frye standard and the relevancy standard.

Appellant urges this court to adopt the Frye standard and hold that the DNA fingerprint evidence should have been suppressed since it has not gained general acceptance in the scientific community. Under the Frye standard, expert testimony based upon a novel scientific technique is admissible only if the underlying scientific principle has gained general acceptance in the particular field in which it belongs. 293 F. at 1014. Appellant relies upon Zani v. State, 758 S.W.2d 233 (Tex.Crim.App.1988), in support of his contention. In Zani, the Court announced that the Frye test was applicable to determine the admissibility of hypnotically induced testimony. Id. at 241. However, Zani was a pre-Rules case and the Court did not address the issue of whether the Frye standard is applicable to post-Rules cases. Consequently, Zani should not be construed as holding that Texas presently adheres to the Frye standard. Kelly v. State, 792 S.W.2d 579, 585 (Tex.App.—Fort Worth 1990, pet. granted). Nevertheless, DNA fingerprinting evidence has been found to be admissible in Texas under the Frye standard. See Mandujano v. State, 799 S.W.2d 318, 321-22 (Tex.App.—Houston [1st Dist.] 1990, no pet.); Glover v. State, 787 S.W.2d 544, 547-48 (Tex.App.—Dallas 1990, pet. granted).

Relying upon Kelly v. State, the State urges this court to instead adopt the relevancy standard. Under the relevancy standard, expert testimony based upon novel scientific evidence is admissible if it is relevant and its probative value outweighs such dangers as the potential of the evidence to mislead the jury. See Tex.R.CRIM. Evid. 401, 403 and 702; Kelly, 792 S.W.2d at 584. Although the Kelly court found the Frye standard to be consistent with the relevancy standard, it is the relevancy standard which must be applied in cases tried after the effective date of the Texas Rules of Criminal Evidence. See Kelly, 792 S.W.2d at 585. We agree. Although we find the DNA fingerprinting evidence to be admissible under either standard in the present case, we hold that the relevancy standard is the proper test to apply in post-Rules cases.

In general, expert testimony is admissible if the witness is qualified as an expert, the testimony will assist the jury, and the probative value of the testimony is not substantially outweighed by its prejudicial effect. See Tex.R.Crim.Evid. 401, 403 and 702; Kelly, 792 S.W.2d at 584; Pierce v. State, 111 S.W.2d 399, 414-15 (Tex.Crim.App.1989), cer t. denied, — U.S.-, 110 S.Ct. 2603, 110 L.Ed.2d 283 (1990). The trial court’s decision to admit the evidence will not be overturned on appeal absent an abuse of discretion. Kelly, 792 S.W.2d at 585.

At the Frye hearing, Dr. C. Thomas Cas-key testified for the State. Dr. Caskey, a board certified internist and molecular geneticist, is chairman of the Institute for Molecular Genetics at Baylor College of Medicine in Houston. Dr. Caskey specializes in DNA research and has never been affiliated with Lifecodes Corporation, the laboratory which did the DNA fingerprint analysis in the present case. Dr. Caskey testified that DNA fingerprinting is a very reliable forensic test. In fact, Dr. Caskey stated that there is no possibility of a false positive DNA match because any technical error in the procedures or degradation of the forensic sample will only lead to no result at all. In Dr. Caskey’s opinion, forensic DNA fingerprinting enjoys widespread acceptance in the scientific community.

Dr. Caskey further testified that he has reviewed Lifecodes’ procedures, internal control systems and operations, and that he found them quite impressive. Dr. Caskey also stated that he has reviewed manuscripts written by Lifecodes’ employees that have appeared in peer group review journals, and that he has found no flaws in their articles or technology. Dr. Caskey testified that Lifecodes’ procedures and quality controls enjoy general acceptance in the scientific community. Moreover, Dr. Caskey reviewed Lifecodes’ testing in the *226 present case. Dr. Caskey found that Life-codes followed their procedures, performed the correct calculations, and reached the correct conclusions.

Appellant did not produce any expert testimony at the Frye
