In order to find out the different types of gametes produced by a pea plant having the genotype AaBb, it should be crossed to a plant with the genotype

Options

  1. AaaBB
  2. BAaBb
  3. CAABB
  4. Daabb

Correct answer

D. aabb

Step-by-step solution

Scientists perform test cross to find out the different types of gametes or the genotype of an unknown individual. Test cross is performed always between the F ₁ heterozygous plants and pure recessive (homozygous) parent plant. So, in the given case AaBb should be crossed with aabb.
