Which claim about crossing over in chromosomes is BEST supported by the diagram?

Question

A.
Crossing over increases genetic diversity through deletion.

B.
Crossing over decreases genetic diversity through mutation.

C.
Crossing over increases genetic diversity by creating new combinations of genes.

D.
Crossing over decreases genetic diversity by inserting nucleotides into gene sequences.

Answer 1

The claim that is BEST supported by the concept of crossing over in chromosomes is:

C. Crossing over increases genetic diversity by creating new combinations of genes.

Crossing over occurs during meiosis when homologous chromosomes exchange segments of genetic material, leading to new combinations of alleles. This process enhances genetic variation in the offspring.
