This in turn led to the idea of genetic linkage, which means that when two genes are closely associated on the same chromosome, they do not assort independently (Morgan, 1911).

The researchers performed genetic analyses of humans and rhesus macaques to ... had previously found a genetic linkage to endometriosis on chromosome 7p13-15 by analyzing DNA from families ...

Thus, without understanding recombination and linkage, we would not be able to perform the genetic screens that allow us to narrow down the search for the figurative needle in a haystack.

They then searched genetic signposts throughout the entire genome in an effort to identify markers that, within the same family, would show that individuals who share the illness also share marker ...
