In guinea pigs coat color is determined by a single gene with two alleles. A guinea pig from a true-breeding black strain is mat
OLga [1]

Answer:

1/3 of black F2 progeny will be homozygous.

Explanation:

Here, BB = black coat color = true breeding dominant black strain

bb = white coat color =  true breeding recessive white strain

When true breeding black and white guinea pigs are mated to give F1 progeny:

BB X bb = Bb ( all black guinea pigs )

When two of the F1 guinea pigs are mated to give F2 progeny:

Bb X Bb = BB, Bb, Bb, bb

F2 progeny has 3/4 progeny as black (BB and Bb) . Out of them 1/3 are homozygous and 2/3 are heterozygous.

Hence, 1/3 of black F2 progeny will be homozygous.
