• B. Male parent - aaBB and Female parent - AaBb
• C. Male parent - AaBB and Female parent - AaBb
• D. Male parent - AABB and Female parent - Aabb

Answer 1

The correct option is A

male parent - AaBb and Female parent - aaBB

The male parent produces 4 types of gametes and hence, its genotype is double heterozygous - AaBb. The female parent produces only one type of gamete. Hence it is double homozygous - aaBB.
