Ok i think i get it now, it helped when i saw the longer version for some reason
So Blue fawn is --> m+/m+, Li+/Li+, C+/C+, e+/e+, Bl/bl, D+/D+, Bu+/Bu+, r+/r+, s+/s+
And Pastel is --> m+/m+, Li+/Li+, C+/C+, e+/e+, Bl/Bl, D+/D+, Bu+/Bu+, r+/r+, s+/s+
& Rouen Clair is--> m+/m+, li+/li+, C+/C+, e+/e+, bl+/bl+, D+/D+, Bu+/Bu+, r+/r+, s+/s+
Blue trout Rouen> m+/m+, li+/li+, C+/C+, e+/e+, Bl/bl, D+/D+, Bu+/Bu+, r+/r+, s+/s+
Saxony Rouen --> m+/m+, li+/li+, C+/C+, e+/e+, Bl/Bl, D+/D+, Bu+/Bu+, r+/r+, s+/s+
So if Say her Rouen is blue Fawn m+/m+, Li+/Li+, C+/C+, e+/e+, Bl/bl, D+/D+, Bu+/Bu+, r+/r+, s+/s+ and crosses it with her
Rouen Clair m+/m+, li+/li+, C+/C+, e+/e+, bl+/bl+, D+/D+, Bu+/Bu+, r+/r+, s+/s+
The Result would be 50% being Bl/bl Li/li (blue fawn with hidden light phase gene)
and 50% being bl/bl Li/li (looks wildtype rouen with hidden light phase gene)
Is there a website or something that you know about that i could read so i can learn the different possibilities of genetics, like the different genotypes for the bibbed and not bibbed and not extended black and extended black etc. ?
