Biology
1 answer:
denis23 [38]3 years ago
4 0

Answer:

Crossing over is the substitution of genetic material in the germline. When egg and sperm cells, also known as meiosis, are formed, paired chromosomes are arranged from each relative in such a way that identical DNA chromosome sequences cross over each other.

Explanation:

Crossing resulting in genetic material shuffling is a significant cause of the genetic difference between descendants.
