Bednarik v. Bednarik
Opinion
Petitioner’s petition for divorce against defendant on the ground of adultery has been met by an answer denying his charges and by a counter-claim seeking a decree of divorce against him. Petitioner alleges that a child born to defendant on August 27th, 1938, is not his child. This charge is specifically denied by the answer. Petitioner’s present application, made before reference under rule 128e, is based upon an affidavit in which he sa3^s: “As the parentage of said child is involved in this suit Í feel that it is absolutely essential to the trial of the same, that one or more blood grouping tests be made of myself, wife and said child in order to determine the parentage.”
The blood grouping tests to which petitioner seeks to subject defendant and the child, together with himself, in an effort to prove that he is not the father of the child, are of comparatively recent development. According to medical authority, hereditary characteristics are determined by units called “genes” which are. said to occur in pairs in rod-like chromosomes of the nuclei cells. The human blood groups follow the chromosome theory. The blood groups, of which there are four, are predetermined by the presence or absence in the chromosomes of two genes called “A” and “B.” Absence of both “A” and “B” is indicated by “0.” Because each somatic cell possesses two of these genes (one from each parent) there are six possible genetic formulae, “00,” “AA,” “AO,” “BB,” “BO” and “AB.” However, since the blood of an “AO” individual is routinely indistinguishable from that of an “AA” individual, and since similarly “BO” blood is routinely indistinguishable from “BB” blood, we have only four demonstrable types of blood (the phenotypes) namely “0,” “A,” “B” and “AB.” There is a wealth of literature [635] on this subject, some of the authorities being gathered in the footnote below.
