If two genes on a chromosome are very close, what happens to the likelihood of their alleles segregating independently during meiosis?

💡 Explanation

The closer genes are on a chromosome, the more likely they are inherited together because the mechanism of genetic linkage physically prevents independent assortment during meiosis; therefore, alleles of linked genes tend to segregate together rather than independently as predicted by Mendel's laws under unlinked conditions.
