Question

the diagram shows the process of crossing over. 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.

Explanation:

Cross - over is a process in meiosis where homologous chromosomes exchange genetic material. This creates new combinations of genes on the chromosomes, thereby increasing genetic diversity. It is not related to deletion, mutation in the sense described in options A and B, nor does it decrease genetic diversity by inserting nucleotides as in option D.

Answer:

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