Opinion
RACANELLI, P. J.
In an action to establish paternity and for child support, the jury returned a special verdict of nonpaternity. On appeal from the judgment entered in favor of respondent, appellant claims prejudicial error based upon (1) exclusion of testimony concerning inconclusive blood test results and (2) misconduct of counsel. We conclude that these claims are without merit; we affirm the judgment.
Statement of Facts
The facts disclosed by the limited record on appeal are undisputed:
At some point during trial appellant made an
in camera
offer of proof that
the medical expert appointed by the court (upon appellant’s motion) to conduct the serologic examinations would testify that as a result of his findings respondent was “among the
Mlá
to 15 percent of the population that could be the father” of the minor child born out of wedlock. In sustaining respondent’s objection to the proffered testimony, the trial court concluded that such evidence merely reflecting that respondent was
included
within the blood groupings consistent with paternity was of no probative value and, in any event, subject to discretionary exclusion due to the likelihood it would unduly influence or prejudice the jury.
The dominant issue presented on appeal is whether blood-test evidence which fails to exclude the alleged father is nevertheless admissible to prove paternity.

Inconclusive Blood-test Results as Evidence of Paternity
The use of properly conducted blood-grouping tests as a reliable scientific method to establish
nonpaternity
of the putative father has been widely accepted in both the scientific and legal communities.

the California Legislature has expressly adopted the prevailing view as a substantive rule of evidence. Section 895 provides as follows:

If the experts disagree in their findings or conclusions, the question shall
be submitted upon all the evidence.”

(Jackson
v.
Jackson, supra, 61
Cal.2d 245, 248.)
The forensic value of the results of medically approved blood tests to conclusively establish nonpaternity derives from the scientific application of immutable laws of inheritance: unless the child and reputed father share a compatible blood group or type, the existence of a paternal relationship is virtually impossible.

supra,
chs. 5-7 and authorities collected.) But the converse principle sanctioning the affirmative use of inconclusive blood-test evidence to prove paternity, as proposed in the original uniform act itself,
is without precedent and generally rejected on the grounds of (1) the highly prejudicial nature of such evidence (Witkin, Cal.

Appellant’s argument favoring the affirmative use of such evidence to establish paternity is ingenuously constructed upon the premise that, absent restrictions imposed by statute or policy considerations, evidence which includes the putative father within a range of statistical probability of paternity should be permitted as relevant evidence (§ 351) tending to prove that disputed fact (§ 210).

v.

(1937) 10 Cal.2d 428 [74 P.2d 1043, 115 A.L.R. 163] and thereafter followed in the celebrated case of
Berry
v.
Chaplin
(1946) 74 Cal.App.2d 652 [169 P.2d 442].
(See Note (1951) 39 Cal.L.Rev. 277.) That the Legislature intended to provide for the use of blood-test evidence only
to exclude
possible paternity is expressly manifested in the language that the “question of paternity shall be resolved accordingly ... [or otherwise] . . . shall be submitted upon all the evidence.” (§ 895.) (Cf. § 896 incorporating the substance of § 895 in permitting a direct verdict of acquittal in criminal actions). In doing so,
the Legislature intentionally omitted the very provision which would have authorized the use suggested by appellant; such circumstance is a strong indication of legislative intent to effect only the changes actually undertaken. (See
Kusior
v.
Silver, supra,
54 Cal.2d 603, 618.) Moreover, our conclusion finds further support in the Legislature’s subsequent enactment of the Uniform Parentage Act (Civ. Code, § 7000 et seq.) again rejecting the affirmative use of blood-test evidence as proof of paternity.
Secondly, assuming arguendo such specific omission may not be so construed to preclude admissibility under general rules of evidence, nonetheless we discern no logical relevance of the inconclusive results which, having failed to establish nonpaternity, are then offered to prove the opposite—in terms of a statistical probability generally applicable to a large-scale random population (see

Crowley, supra,
64 Cal.2d 647, 656) or other corroborative proof as demonstrated in the cases relied upon. The offer of proof as made is woefully inadequate to establish the necessary preliminary foundation for such concededly novel theory of admissibility. (See generally Witkin, Cal. Evidence (2d ed. 1966) §§ 206, 408-409, pp. 188, 366-368.) Nor does.the sparse record on appeal offer other evidence even tending to corroborate such generalized inconclusive results.
Finally, in view of the recognized danger of unduly influencing lay jurors by the presentation of so-called “scientific” evidence likely to create a “misleading aura of certainty”
(People
v.
Kelly, supra,
17 Cal.3d 24, 32), we cannot say on the brief record presented that the determination of the experienced trial judge to exclude such evidence—assuming its admissibility—constituted an abuse of the broad discretion vested under section 352.
II.
Misconduct of Counsel
Appellant’s contention of misconduct relates to certain comments of counsel on two occasions during closing argument. Preliminarily, we
observe that appellant’s failure to request timely admonition to correct the asserted misconduct precludes our consideration on appeal in the absence of demonstrable prejudice.

Judgment affirmed.
