Question

which evidence from the model supports the students claim? a chromosomes exchange genetic material in step 3. b chromosomes are replicated in step 1. c chromatids separate in step 5. d chromosomes pair in step 2.

Explanation:

Chromosomes exchanging genetic material (cross - over) in meiosis leads to genetic variation. This is a key process that can support claims related to genetic diversity. Replication (B) just duplicates genetic material, separation of chromatids (C) is part of cell division to distribute genetic material, and chromosome pairing (D) is a step before cross - over but doesn't directly show genetic material exchange for variation.

Answer:

A. Chromosomes exchange genetic material in step 3.
