Opinion

OPINION

MALONEY, Judge.

Appellant was indicted and convicted in Freestone County on a charge of Capital Murder. TEX.PENAL CODE ANN. § 19.-03(a)(2). The indictment alleged that appellant caused the death of the deceased by beating and striking her with a blunt instrument in the course of committing a sexual assault. The jury answered the three issues submitted to it in the affirmative and the trial court assessed the death penalty. TEX. *422 CODE CRIM.PROC.ANN. art. 37.071. Direct appeal was had to this Court. TEX. CODE CRIM.PROC.ANN. art. 37.071(h). Appellant brings five points of error in this appeal. 1

In his first and second points of error appellant complains of the admission of evidence and testimony relating to DNA testing in which a comparison was drawn between appellant’s genetic characteristics and the genetic characteristics of sperm found on the deceased’s body. 2 Appellant claims that such evidence was improperly admitted because it failed to meet the standards set forth in Frye v. United States, 293 F. 1013 (D.C.Cir.1923) and United States v. Downing, 753 F.2d 1224 (3rd Cir.1985). 3

We recently addressed the admissibility of DNA evidence and the viability of the “Frye test”, concluding that Rule of Criminal Evidence 702 governs the admissibility of novel scientific evidence, including evidence of DNA testing. Kelly v. State, 824 S.W.2d 568 (Tex.Crim.App.1992). Pursuant to Rule 702, the proponent of the scientific evidence must prove by clear and convincing evidence outside the presence of the jury that the proffered evidence is reliable and relevant. 4 Id. at 573; Fuller v. State, 827 S.W.2d 919, 930 (Tex.Crim.App.1992), petition for cert, filed (June 23, 1992). Once determined reliable and relevant, such evidence is admissible unless the trial court determines that its probative value is out *423 weighed by any of the factors identified in Rule of Criminal Evidence 403. 5 Kelly, 824 S.W.2d at 573; Fuller, 827 S.W.2d at 930.

The testimony concerning admissibility of DNA evidence was by agreement presented in the presence of the jury. 6 The State called Dr. Thomas Caskey, M.D., a medical geneticist and chairman of the Molecular Genetics Department at Baylor College of Medicine, who testified that the particular forensic technique utilized to analyze DNA, “restriction fragment length polymorphism” (RFLP) is the form of analysis employed by Lifecodes, the company that conducted the DNA tests in the instant case, and that RFLP is a reliable and widely accepted technique in the scientific community. Caskey testified that the United Kingdom’s Scotland Yard has utilized the RFLP technique for some time and that the FBI is on the verge of adopting the RFLP method. Caskey further testified that he was familiar with Lifecodes’ laboratory protocol and that the protocol was more than sufficiently rigorous to ensure reliable results. According to Caskey, a false positive finding was impossible because if the procedures were not correctly followed, no match could be obtained. Dr. Kevin McElfresh, Ph.D., a Lifecodes scientist and geneticist, called by the State testified as to the wide and virtually undisputed acceptance in the scientific community of the RFLP technique. McElfresh testified at length about Lifecodes’ procedures, its method of analyses, that the procedures utilized had the ability to exclude suspects absolutely and that a false positive result was impossible. McElfresh further testified about Life-codes’ data base and the procedure utilized in determining the statistical frequency that a particular DNA fragment is found in the general population; that the chances of the DNA match found between appellant’s DNA and the evidence DNA occurring in the North American Black population is one in ninety-six million and is one in seventy-seven million in the North American Caucasian population. Lorah McNally, the Lifecodes employee who conducted the analysis of the samples submitted in the instant case, testified about the process she had used in arriving at' her conclusions. She holds a bachelor’s degree in science and a master of science degree in forensic science. McNally stated that she isolated the DNA from sperm samples taken from the victim and compared those findings with DNA that she isolated from blood samples taken from each suspect, including appellant. 7 She testified that each individual tested, except appellant, was absolutely excluded as a suspect and that appel *424 lant’s DNA matched on all three “probes” tested with the DNA extracted from the semen. All of the State’s witnesses were rigorously cross-examined on the potential for human error and questioned about the scientific certainty of the process used.

Following the State’s evidence, appellant moved for an instructed verdict, alleging that the State’s case rested entirely on the DNA evidence which did not satisfy the Frye test or the Rules of Evidence. The trial court overruled appellant’s motion. Appellant then called Dr. Simon Ford, Ph.D., a molecular geneticist. Ford testified that he had completed his post graduate work in biochemistry, specifically studying the genetic material characteristic of certain bacterial contaminants. Although Ford stated that the basic technology involved in DNA typing is “very settled”, he related problems that might occur when analyzing a forensic sample. Ford also testified that the data analyst must make certain “subjective” calls. Ford stated that he would not be comfortable finding appellant guilty solely on the basis of the DNA test results. On cross-examination Ford agreed that the chances of a false match due to contamination in Lifecodes’ technique would happen “very infrequently.”

Following the admission of all of the testimony from both parties on the DNA evidence and after taking appellant’s objections to the evidence under advisement, the Court held: “the evidence is relevant, reliable and probably helpful for a fact finder [and that] ... the technique is generally accepted in the scientific community in which it’s applied.” Viewing the evidence in the light most favorable to the trial court’s finding, we hold that the trial court did not abuse its discretion in finding that the State proved by clear and convincing evidence that the DNA evidence was relevant and admissible. See Kelly, 824 S.W.2d at 573-74; see also Fuller, 827 S.W.2d at 930. The State’s witnesses, who were all exceptionally well-qualified, testified that the RFLP method of DNA forensic analysis utilized in the instant ease was well accepted in the scientific community.
