Abstract

Testicular material from a normal ram (54XY), three rams heterozygous (53XYt1) and one ram homozygous (52XYt1t1) for the Massey I (t1) translocation was examined. The autosomal non-disjunction in the normal ram was 2.0% compared to a mean of 6.1% in the heterozygous animals. In the homozygous animal there were adhesions of the tunica vaginalis to the cauda epididymidis and extensive spermatogenic arrest.

摘要

对一只正常公羊（54XY）、三只杂合子公羊（53XYt1）和一只纯合子公羊（52XYt1t1）（携带梅西I型（t1）易位）的睾丸组织进行了检查。正常公羊的常染色体不分离率为2.0%，而杂合子动物的平均不分离率为6.1%。在纯合子动物中，鞘膜与附睾尾部存在粘连，且生精过程广泛停滞。
