Question

What would be the result if synapsis and crossing over failed during meiosis I?
Options
A There would be no change in chromosome number
B Genetic variation among gametes would significantly decrease
Correct Answer
C Mitotic errors would be more likely
D Cells would become diploid instead of haploid
Correct Answer

Option B is the correct answer.

Detailed Explanation

Synapsis and crossing over are key mechanisms for generating novel allele combinations. Their failure would drastically reduce genetic diversity in the resulting gametes.

Hint

These processes are central to creating new genetic combinations.
