Apologies for the confusion. I made an error in my previous response.

In a dihybrid cross, each parent has two different alleles for each gene. When cross-pollinating JjQq and JJQq, there are four possible allele combinations for the offspring: JQ, Jq, jQ, and jq.

The genotype JJQQ requires the offspring to inherit the J allele from one parent and the Q allele from the other parent.

In this case, there is no possibility for an offspring with the JJQQ genotype because neither of the parents has the QQ genotype.

Therefore, the correct answer is:

D. 0
