A heterozygous brown-eyed rabbit is crossed with a homozygous dominant brown eyed rabbit (B = brown-eyed, b = red-eyed). What percent of their offspring are predicted to be homozygous dominant?
a. 100%
b. 25%
c. 0%
d. 50%



Answer :

Answer: b. 50%

Explanation:

When a heterozygous brown-eyed rabbit (Bb) is crossed with a homozygous dominant brown-eyed rabbit (BB), we can use the Punnett square to predict the offspring's genotypes.

The Punnett square for this cross would look like this:

     B   |   b

----------------

B |  BB |  Bb

----------------

B |  BB |  Bb

----------------

From the Punnett square, we can see that 50% of the offspring are predicted to be homozygous dominant (BB), so the correct answer is:

a. 50%

Hope this helps!
