I diagrammed this so that the different genes stood
stood out better for me. I have bad vision. No offence is meant for anyone other than myself.
If you breed silvers with the correct genotype, you will get 100% silver.
If the original silvers were bread in a way that the genes only express the desired color, without being able to pass that trait on to the next generation, you will get a mix.
I have only done the math on magpie, but you can see how it works.
For example, if you breed pied and bibbed, you will get what "expresses" the magpie color, but the next generation would me mixed colors
Pied M*M* Li*Li* ee* bl*bl * cc *BB* RR* DD*Bu Bu
bib M*M* Li*LI* EE* bl*bl * cc * BB* rr * D* Bu
ofspring
male M*M Li Li Ee * bl bl *CC *BB *Rr *DD *bu bu hen M*M Li Li Ee *bl bl *CC *BB *Rr *D *bu
True magpie
male M*M Li Li EE bl bl CC *BB RR DD bu bu
hen M*M Li Li EE bl bl CC *BB RR D bu
1. The Pied Drake has two ressesave extended black genes (ee)
2.The bibbed hen has two Domanent
extended black genes (EE)
3. That combination creates one recesave and one dominant in all of their ofspring (Ee)
A dominant gene will always express
over a recessive, so you get the black for magpie
4. But since they each carry the resesave They can each throw a resesave gene (ee) and the chicks will not be magpie.
The true magpie has two Dominant (EE)
There are also differences in the Rr, D and bu genes those can be explained the same way, and how genes express themselves
