Aneuploidy

APBIO-LIZGVZ

This phenomenon MOST likely resulted from

A

nondisjunction, an error in cell division.

B

double fertilization, two sperm fertilizing the same egg.

a sex-linked disorder, in which the gene causing the problem is on the X-chromosome.

D

epistasis, in which the function of one gene affects the expression of another.
