Answer:

The correct option is <em>B. 25 %</em>

Explanation:

 A heterozygous type can be described as the type in which both the alleles of a gene are different. If both the alleles of a gene are similar in an organism, then the person is said to be homozygous for the trait.

In the above question, two heterozygous parents are to be cross- bred to check the probability of them producing homozygous alleles (AA).

A punnet square made will show the following results:

       A     O

A     AA    AO

B    BA     BO

Hence, there will be 25% chance that the offspring produced could be homozygous AA.
