After I have produced japan blue males from galaxy cross I have made (you can read about it here) I assumed that F1 females will carry on one of X chromosomes (after father) Schimmelpfennig platinum (I will call this gene Sc as well). Well testing this out was bigger temptation than pursuing galaxy roundtails sooo 2 new crossess I work on.
I have raised a nice group of young singapur blues. I am very interested in testing them with X linked Sc – theorhetical goal is a green forebody guppy! :). So I decided to cross F1 females which can carry X linked Sc with my singas.
In the second cross I use also those X-linked Sc females:
Take a closer look on this male peduncle – he has this golden shine also there – it is useually characteristic for Schimmelpfennig platinum forebody. I hope that by adding X linked Sc I will stronger this effect somehow.
