Q. 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

A) aaBB
B) AaBB
C) AABB
D) aabb
Explanation

[Solution from source] A test cross with the double recessive aabb works because that parent gives only ab gametes, so each offspring's phenotype shows exactly which gamete came from the AaBb plant. Dominant alleles in the tester would hide the recessive gametes. Answer (4).
