Question

Crossing over is advantageous to cells because it creates genetic variation
a-true
b-false

Answer 1

Crossing-over is the process during meiosis when chromosome pairs exchange DNA, creating genetic variation.

Step-by-step explanation:

Crossing-over is the process that occurs during meiosis when chromosome pairs exchange DNA. This process increases the variance of genetic combinations in the haploid gamete cell, resulting in genetic variation.
