Question

Someone please help!

Answer 1

1.

a.  Bb

b. bb

c. Gray, because the male is homozygous recessive, which indicates the recessive trait is black.

d.  Gray-Female, Black-Male

e.      B       b

    b  Bb     bb

    b  Bb    bb

f.  There's a 50% chance the babies will be heterozygous (for gray) and there's a 50% chance the babies will be homozygous recessive for black.

g. There's a chance that all four offspring won't adhere exactly to the ratios predicted by the Punnett Squares, because male offspring can only have one trait (on the X).

Hope this helps. I hope you understand that heterozygous is (Big Letter & Small letter) and homozygous is either: Big Letter Big Letter OR Small Letter Small Letter. Have a great night and I hope you are successful in your class!
