Japan blue

Japan blue is easly identified by blue coloration of peduncle. Probably comes from feral population of  Poecilia reticulata living in Japan waters. It is y-linked. Some breeders belive it is possible to jump it on X chromosome – others belive it is not possible. It is worth mentioning that population very similar in look to […]

Magenta

Very interesting gene. Autosomal dominant. It highlights metallic shine. It causes poliferation of melanophores – and probably that is how it influence metallic colors as well (melanophores and guanophores – responsible for shiny cover – seems to stay in strong connection, not only in case of this gene). It creates effect of pearl mass on […]

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 […]
