Crossing over occurs in prophase I of meiosis I. Which is an advantage of crossing over?

a. it keeps genetic variation to a minimum to enable offspring a better chance of surviving.

b. combining DNA from two parents in a single chromosome reduces genetic variation in sexual life cycles.

c. it results in recombinant chromosomes where all chromosome carry genes from either the mother or father

d. each chromosome in a gamete cannot be exclusively maternal or paternal

The advantage of crossing over is that it results in recombinant chromosomes where all chromosome carry genes from either the mother or father (option C).

What is crossing over?

Crossing over is a phenomenon whereby non-sister chromatids of homologous chromosomes exchange genetic material.

Crossing over occurs in the prophase I stage of meiosis and results in the formation of daughter cells that are genetically different from parent cells.

Therefore, the advantage of crossing over is that it results in recombinant chromosomes where all chromosome carry genes from either the mother or father.
