Abstract:

Sex genotypes in mature androgenetic and control rainbow trout Oncorhynchus mykiss were determined using primed in situ labelling (PRINS) detection of 5S rDNA sequences on the X chromosomes. Three sex genotypes, corresponding to phenotypic sex, were revealed: female XX, male XY and supermale YY.
