Assuming sexual reproduction and that no mutations have occurred, which of the following offspring genotypes is not possible for the given parent genotypes?

a. genotype a

b. genotype b

c. genotype c

d. genotype d

The answer is; B

This genotype is similar to that of one parent. It assumes that nondisjunction of chromosome did not happen and there was no fusion of gametes. The offspring cannot have exact genotype as one parent in sexual reproduction, In sexual reproduction, the offspring gets half of its chromosomes from each parent. This is why the chromosome number is reduced by half in the formation of gametes through the process of meiosis.

not too sure but maybe in the hot springs.
