Cytogenetical characteristics of the embryos between diploid female and triploid male in rainbow trout

Abstract

The eyed embryos of raindow trout between diploid female and triploid male were obtained. The chromosome preparations of these embryos were made by the short-term culture method. There were two groups, namely 72 -79 of chromosomal numbers (18 individuals) and 100-108 (3 individuals). Judging from numbers and constitutions of the chromosomes, it is presume that the chromosomes of the triploid during spermatogenesis divide into two by near the common way. © 1987, The Genetics Society of Japan.
