A human male produces sperms with the genotype $A B, A b, a B$, and ab pertaining to two diallelic characters in equal proportions. What is the corresponding genotype of his person'?

• A

  AaBB
• B

  $\mathrm{AABb}$
• C

  AABB
• Correct answer
  D

  AaBb.

Solution

As the person produces sperm having both the alleles for both the characters. So the person must be heterozygous for both the genes, hence, the genotype will be $\mathrm{AaBb}$.

Hence, the correct answer is option: 'D'.
