Answer: Option A) sister chromatids
In mitosis, each chromosome is made up of sister chromatids that carry the same alleles.
Explanation:
During the fourth phase of mitosis (Anaphase) the sister chromatids part company and migrate to the opposite poles, each with the same alleles since no crossing over occurred.
Thus, mitosis results in two daughter cells that have the same chromosome make-up as the original parent cell.
