The distribution of diploid rabbit spermatozoa in the female tract after artificial insemination

The distribution of diploid rabbit spermatozoa in the female tract following artificial insemination is generally similar to that after natural mating, except that the incidence of diploid spermatozoa in the female tract is generally greater after A.I. than after coitus, despite a lower proportion of diploids in the semen used for A.I. Therefore the chances of the formation of triploid zygotes due to fertilization of normal eggs by diploid spermatozoa may be increased following A.I., although the frequency of such zygotes would still be very low.
