Question

The diagram shows the process of crossing over
Which claim about crossing over in chromosomes is best supported by the Diagram
Crossing over increases genetic diversity through deletion
Crossing over decreases genetic diversity through mutation
Crossing over increases genetic diversity by creating new combinations of jeans
Crossing over decreases genetic diversity by inserting nuclectides into gene sequences

Answer 1

The best-supported claim about crossing over in chromosomes, based on the process described, is:

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 is a key mechanism for genetic diversity in sexually reproducing organisms. The other claims mentioned do not accurately describe the role of crossing over in creating genetic diversity.
