Hybrid birds between Northern bobwhite and Masked bobwhite, 2019

I firstly would like to precise that the below-pictured birds were not bred in my aviaries but well bought from another breeder.
They normally should have been pure specimens of the Masked bobwhite (Colinus virginianus ridgwayi) but a quick 5 seconds examination confirmed that there is without any doubt blood of Northern bobwhite (Colinus virginianus) mixed inside…
I have no idea how much %, F1 or F2? and the exact mating(s) done…



This is a little “head comparison” collage I made of the two pure species and my “hybrid” bird in the middle… I think it helps to understand better!

From left to right: Masked bobwhite, hybrid, Northern bobwhite

It is quite difficult to determine how much % blood of common Northern bobwhite (Colinus virginianus) is present in the genotype of those hybrid birds but, in my opinion, the breeder crossed more that one time …
I will not try to make the same collage with female heads because the difference is most on the back for hens.
