Asian blau

Asian blau. Called blue cheat. It is a dominant gene, which is pretty interesting. In heterozygotous state it lowers synthesis of red erythrophores and probably in much lower level also yellow xantophores. It also slightly modifies guanine presence. In homozygotous state effect is much more visible as it almost completly removes red erythrophores and yellow […]

Supressors part 1

In my hobby hatchery I play with few genes that can be called supressors. Supressor gene means lower expression of a certain trait. In this little series I will present supressors of tail fin. So genes that supress tail shape – from big tail fin to short tail fin – in my breeding program from […]
