mottled x dominant white

[Del Boy]

I have a few black mottled x dominant white birds in the yard. I wonder what is the chance of getting some nice dark black mottled birds if I breed them togeather. The birds I have are almost completely white but all carry mottled .
thanks

there is no chance in the first generation that you will get any thing but white...but if the first gen breed back to the mottled them you could get some mottled some white and most would be black.

less than 7%(6.250) if your birds were all black(with one copy of mottling) your odds would jump to 25%, but you have heterozygous dominant white and this will hide many mottled birds you may produce

No chance? come on, statistically there is chance(around 7%) he would need to hatch at least 40 to expect one, but NO Chance?

according to the chicken calculator http://kippenjungle.nl/kruising.html no there is no chance in the first gen.

know the second Gen. if you breed them back to a mottled 1 out of 8 chicks should be black

check again! and remember, he is using two birds(male and female) with one copy of dominant white and one copy of mottled, so yeah there is a chance(small one but there is)

oh yes I see now...I miss read and thought original poster wanted to know what the chicks would look like if he crossed a mottled and a dominate white.
