Linkage

Definition(s)

The tendency for genes or segments of DNA closely positioned along a chromosome to segregate together at meiosis and therefore be inherited together

Linkage is the close association of genes or other DNA sequences on the same chromosome. The closer two genes are to each other on the chromosome, the greater the probability that they will be inherited together.
