Complete the following monohybrid cross.

Question

Two parents that are heterozygous for brown eyes. Be sure to identify the genotypes of the parents, complete the Punnett square, identify the phenotypes with genotypes and the ratio of the phenotypes.

What percent of the offspring have blue eyes?

My answer: 25% of the offspring would have blue eyes if the parents are heterozygous.
What I need help with: How do I fully answer the question? Please help me.

Answer 1

Assuming that both of the heterozygous parents have both blue and brown genes, and blue is recessive to brown, e.g., Bb.

Construct a Punnett square and continue from there.
