Question

use the information and model to answer the following question.
what process is missing from the image that could further increase genetic variation within the four daughter cells? (aks 6a1)
a dna replication should occur for all chromosomes.
b segregation should occur for all chromosomes.
c crossing over should occur between homologous chromosomes.
d protein synthesis should occur between homologous chromosomes.

Explanation:

To determine the missing process for increasing genetic variation, we analyze each option:

• Option A (DNA replication) duplicates DNA but doesn’t increase variation (produces identical copies).
• Option B (Segregation) is normal in meiosis but doesn’t create new allele combinations.
• Option C (Crossing over) occurs between homologous chromosomes, exchanging genetic material and creating new allele combinations, thus increasing variation.
• Option D (Protein synthesis) is about making proteins, not genetic variation.

So crossing over (Option C) is the process that increases genetic variation.

Answer:

C. Crossing over should occur between homologous chromosomes.
