Frizzle sizzle

[Squirrelfox]

silkie is recessive. You want two copies so that you have silkie feathers.

Frizzle is dominant, and you really only want one copy anyway.

I have no idea what the genetic letters are, so I'm making up my own: silkie, s. Hard-feather, S. Frizzle, Fr; non-frizzle, fr.

So you've got your first generation cochin/silkies. They're frizzle (Fr/fr) and carry one copy of the silkie gene (S/s)

If you breed them to their siblings, you'll breed Fr/fr to (preferably) fr/fr, and S/s to S/s.

Are you familiar with a punnet square? If not, then breeding Fr/fr to fr/fr will result in half of them inheriting Fr. Half should be Fr/fr, and half should be fr/fr. Half frizzled, half non-frizzled.

Breeding your F1s, S/s to S/s will give you these four outcomes: S/S, S/s, S/s and s/s. Of those four chances, three aren't silkied. You'll only have a quarter of the offspring being silkies, and you won't know which one is S/S, which, no matter what you do, will never produce silkied offspring itself.

Since only half of your F2 chicks will be frizzled, one chick in eight should, on average, be both silkied and frizzle. And then you have to account for male/female ratios.

On the other hand, if you breed, S/s (your chicks) to s/s (your parent silkies) half will be S/s, and half will be s/s. All of the offspring will be usable in a breeding program to produce silkied birds, and half will be silkied.

1/2 silkied 1/2 frizzled, 1/2 female should make it so that one in eight of your F2 offspring are silkied, frizzled females.
