WebOct 3, 2024 · Crossing over occurs at 4 strand-stage between non-sister chromatids. Crossing over can take place in more than one place. Each chromatid moves individually in every four haploid gametes. Four types of gametes are formed; Two gametes have parental combinations of linked genes, i.e., AB and ab, Two with recombination of genes i.e., Ab … 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. B.
