The diagram shows the process of crossing over.

Question

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

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 best-supported claim about crossing over in chromosomes is:

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

Crossing over during meiosis results in the exchange of genetic material between homologous chromosomes, leading to new combinations of genes and increasing genetic diversity in the offspring.
