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.

Answer 1

The best-supported claim about crossing over in chromosomes is C. Crossing over increases genetic diversity by creating new combinations of genes.

During crossing over, segments of DNA are exchanged between homologous chromosomes, leading to new combinations of alleles in the resulting gametes. This process contributes to genetic diversity in offspring.
