Opinion

JACOBSON, Judge.

The classic confrontation of advancing medical technology versus judicial presumptions is presented in this case of first impression in Arizona arising out of an action in Pima County dealing with the use of blood grouping tests in paternity actions.

In consideration of the welfare of the child herein involved, we have refrained from naming the parties in this decision. The appellant-defendant and appellee-plaintiff, were married on May 13, 1966. Marital difficulties arose almost immediately culminating in a separation of the parties on June 12, 1966. At this time the plaintiff moved from defendant’s household and the parties agreed to a trial separation for six months, a condition being the abstinence from sexual relations during this period.

During the trial separation period the parties dated each other frequently but both agreed the condition above referred to was followed. The observance of this condition of abstinence continued until the early morning hours of January 1, 1967. Plaintiff testified that following a dance on the evening of December 31, 1966, an act of sexual intercourse occurred between the parties. Defendant denied such an occurrence.

Because of increasing marital difficulties and the apparent failure of the trial separation, plaintiff filed suit for divorce on January 10, 1967. The divorce was uncontested by defendant and a decree of divorce was entered on February 10, 1967, granting plaintiff an absolute decree of divorce and restoring her maiden name. This decree was silent as to any children or plaintiff’s condition of pregnancy. In May of 1967, plaintiff’s doctor confirmed that she was pregnant. The testimony is in dispute as to whether defendant acknowledged parentage at this time; however, the matter not being resolved, plaintiff on September 1, 1967, filed a Petition for Modification of the decree of divorce seeking medical expenses, lying-in expenses and support for the expected child. Defendant appeared and denied paternity of the child. On September 20, 1967, plaintiff gave birth to a full-term, nine-pound two-ounce baby. 1 At the time of the trial of this matter, the child was approximately two and one-half months old.

At the close of defendant’s case, defendant moved for a directed verdict based primarily upon the testimony of Dr. Louis Hirsch, a pathologist. He testified that as a result of blood grouping tests taken from the plaintiff, defendant and the child, defendant was medically excluded as the father of the child. The motion was denied and the matter submitted to a jury who found that the defendant was the father of plaintiff’s child. Defendant duly moved for judgment N.O.V. or for a new trial, again urging the exclusionary testimony of Dr. Hirsch. All of defendant’s post-trial motions were denied and this appeal followed.

The factual situation presented by this case brings into sharp focus the weight to be given by Arizona courts to exclusionary blood grouping tests in paternity actions. On the one hand is the fact, implicit in the jury’s findings of paternity, that intercourse between the defendant and plaintiff occurred at a time during which conception was possible; that defendant is not impotent ; and that at the time conception could *498 have occurred plaintiff and defendant were married. Standing alone against this evidence is the exclusion of defendant as the father because of blood grouping'tests.

Since this is a case of first impression in Arizona, an explanation of blood grouping tests is in order. Blood groups refer to the properties of red blood corpuscles which cause them to clump together when in contact with appropriate anti-sera, the process being known as “agglutination.” A substance in the blood cells which is capable of producing an element having the power of agglutination is designated as one of the agglutinogens. The substance in the anti-sera which causes agglutination is designated as an agglutinin. These substances — agglutinogens and agglutinins— are capable of identification through their reaction to one another. By classifying these reactions, scientists have established systems of blood groupings to include all human beings. The most familiar of these types are the ABO group, the MN type and the Rh type. (See K. B. Brilhart, M. D., Medical Evidence to Exclude Paternity, 1 Ariz. Bar Journal 19 (June, 1965).)

The agglutinogens and agglutinins present in an individual’s blood are hereditary characteristics and therefore capable of being used for identification purposes. To understand adequately how identification can be possible, it is necessary to explain, briefly, the genetic laws originally formulated by Gregor Mendel (Mendelian Laws). A person’s biological makeup (color of hair, physical characteristics, blood types, etc.) becomes fixed at the time of impregnation of the mother’s ovum by the father’s sperm. The inheritance of these biological substances is governed by genes, which occur in rod-like groups or lumps called chromosomes. When reproduction takes place the two groups of chromosomes separate, each joining with some.other chromosome to later form a new cell. This pairing of chromosomes takes place according to the biological character of each chromosome or gene. For example, the maternal chromosome that contains the color of eyes pairs off with the corresponding paternal chromosome controlling eye color, and the maternal blood type chromosome pairs off with the corresponding paternal blood type combination. Thus, if the blood groupings of both mother and father are known, the blood grouping of the child may be predicted. Conversely, if the blood groupings of one parent and the child are known, the blood grouping of the other parent can also be determined.

Both the existence of various blood types and Mendel’s Law of Hereditary Characteristics are universely accepted in scientific fields. 1 Wigmore on Evidence Section 165a (3d ed. 1940).

With this background in mind, the testimony of Dr. Hirsch, as to the result of blood grouping tests, shows that defendant was not excluded from an analysis of the ABO Blood grouping, nor the MN blood typing, but was excluded under the Rh typing:

“(Dr. Hirsch) The putative father was grouped as a little “c”. The putative mother was grouped as a big “C” and a little “c” and the child was grouped as a big “C” * * *
“The child has two big “C’s”; consequently there was no place for this child to have gotten two big “C’s”. He got— we know where he got one, from the mother, because it was demonstrated there but it must have gotten the big— 'other big “C” elsewhere.
“Q: In other words, it would have been impossible for that child to have gotten a big “C” from the defendant in this case,
Mr__?
“A: Yes, sir.
“Q: Because he didn’t have a big “C”?
“A: That’s correct.”

By judicial decision or by statute, most states admit evidence of blood grouping tests to disprove paternity, but not to show paternity. Kusior v. Silver, 54 Cal.2d 603, 7 Cal.Rptr. 129, 354 P.2d 657 (1960); Beck v. Beck, 153 Colo. 90, 384 P.2d 731 (1963); Retzer v.
