#14. Use the following information to answer the next two questions.

In chickens, black feathers (B) are dominant over white feathers (b). The sex ratio of chickens is 50:50.

If two offspring result from the cross between a heterozygous hen and a heterozygous rooster, what is the probability both chicks will have the same homozygous dominant genotype (BB)?
Select one:
a. 0.250
b. 0.125
c. 0.500
d. 0.0625
I believe the answer is a because half will be hen and the other half would be the rooster same thing if a couple were to have a baby boy or a girl. it would be 50/50 percent chance. and 0.50 x 0.50=0.250.

#15.If a heterozygous black hen mated with a white rooster, what is the probability an offspring would be a black rooster?Select one:a). 0.25.b). 0.13.c). 0.75.d). 0.50. I think it is b? not sure about this one at all.
