Question

1. how does aneuploidy arise from mitosis failure? a. by an unequal distribution of chromosomes between daughter cells b. by the formation of extra centromeres c. through the uncontrolled division of cytoplasm d. through the overproduction of spindle fibers

Explanation:

Aneuploidy is an abnormal number of chromosomes in a cell. In mitosis, when chromosomes are not evenly distributed between daughter cells during cell - division, aneuploidy can occur. Spindle - fiber overproduction, uncontrolled cytoplasm division, or extra centromere formation are not the main ways aneuploidy arises from mitosis failure. The key is improper chromosome segregation.

Answer:

a. By an unequal distribution of chromosomes between daughter cells
