Linkage and crossing over are key concepts in genetics. Linkage refers to genes that are located close together on the same chromosome, making them likely to be inherited together. These linked genes do not follow Mendel’s law of independent assortment. However, during the process of meiosis, crossing over can occur.

This is when segments of homologous chromosomes exchange genetic material, creating new combinations of genes. Crossing over breaks the linkage between genes, increasing genetic diversity. The farther apart two genes are on a chromosome, the more likely crossing over will separate them, resulting in greater variation in offspring traits.
