Chromosome morphology during meiosis of normal and Robertsonian translocation-carrying rams (Ovis aries).


A detailed description is given of the meiotic chromosomes of the normal ram (54,XY) and of the chromosomes at diakinesis-metaphase I in rams heterozygous for the t1, t2 and t3 and homozygous for the t1 and t3 Robertsonian translocation chromosomes. Analyses were made on diakinesis-metaphase I chromosomes in 309 cells from normal rams and 2402 cells from… (More)
