Well there are two possibilities.
Big letters are dominant, small letters are reccesive.
1.
The male has Dd
Th female has Dd
This means they are both heterozygous.
The offspring would be :
DD (dark ), Dd ( Dark) , dd (Light), and Dd dark. 25% light
2. The male ha Dd
The female has dd
The offspring would be Dd (dark), Dd (dark), dd (light) , dd light 50% light.
??? Are you meaning recessive white? That symbol is c+ (not-recessive white is C+, for coloured). My 50/50 was for the white hens bred with a heterozygous cock. Breed two hets together and you get the 25/50/25 percentages. Considering that the flock is mixed, you will get some variation in the numbers. Also, the probability is for each EGG, not exactly the same as the percent of all eggs combined. With large numbers the differences between these two meld together and become pretty indistinguishable.
