Question

a model of cell division is shown here. a student evaluates the model and makes the claim that the cell division increases genetic variation in the daughter cells. which evidence from the model supports the students claim? a chromosomes pair in step 2. b chromatids separate in step 5. c chromosomes are replicated in step 1. d chromosomes exchange genetic material in step 3.

Explanation:

Genetic variation in cell division is primarily introduced through processes like crossing over, where chromosomes exchange genetic material. Among the options, exchanging genetic material directly increases variation.

Answer:

D. Chromosomes exchange genetic material in step 3.
