E) they code for traits that affect the same part of the body.

Question

Quizplus · Accepted Answer

Genes that are located far apart on the same chromosome are more likely to assort independently due to the phenomenon of crossing over during meiosis. Crossing over occurs at chiasmata, which are more likely to form between genes that are far apart from each other on the chromosome. This exchange of genetic material between homologous chromosomes can result in new combinations of alleles and increase genetic diversity. Genes that are next to or nearby each other on the same chromosome are more likely to be inherited together and less likely to assort independently. The similarity of traits or their effects on the body does not necessarily affect the likelihood of independent assortment.
