WebWhy does crossing over occur more often between two distantly linked genes than between two closely linked genes on the same chromosome? A. Crossing over frequency depends on long-range ordered hydrophobic forces. Two genes that are far apart are more likely to have a crossover between them than two genes that are close together.

WebSep 11, 2024 · Crossing over is a cellular process that happens during meiosis when chromosomes of the same type are lined up. When two chromosomes — one from the mother and one from the father — line up, parts of the chromosome can be switched. The two chromosomes contain the same genes, but may have different forms of the genes. WebSep 4, 2024 · This exchange of genetic material can happen many times within the same pair of homologous chromosomes, creating unique combinations of genes.
