Abstract excerpt
Analysis of meiotic tetrads is routinely used to determine genetic linkage in various fungi. Here we apply tetrad analysis to the study of genetic linkage in a vertebrate. The half-tetrad genotypes of gynogenetic diploid zebrafish produced by early-pressure (EP) treatment were used to investigate the linkage relationships of two recessive pigment pattern mutations, leopard (leo) and rose (ros). The results showed...
