Question

Genes A and B are on the same chromosome. What gametes could an individual with the allele combination AABB produce?

a) AABB
b) A
c) AB
d) B
e) AAB

Answer 1

An individual with the genotype AABB, where both genes are on the same chromosome, can only produce gametes that contain the AB combination of alleles.

Step-by-step explanation:

When considering an individual with the allele combination AABB, where genes A and B are on the same chromosome and both are homozygous dominant, the types of gametes this individual can produce is limited. Since there are no alleles for recombination due to the homozygous nature of both genes, the individual can only produce gametes with AB alleles.

This is due to the fact that during meiosis, the process that forms gametes, each gamete receives one allele from each gene. Since there is no other allele present for genes A and B, the only possible gamete this individual can produce contains the existing alleles, which are A and B (AB).
