Biology Question on Principles of Inheritance and Variation
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
Answer
aabb
Explanation
Solution
When you cross a pea plant with the genotype AaBb (heterozygous for both genes) with a plant of the genotype aabb (homozygous recessive for both genes), you can analyze the possible combinations of alleles in the offspring to determine the types of gametes produced by the AaBb plant. This type of cross helps reveal the segregation of alleles during meiosis.
So, the correct oiption is (D): aabb
