Question

Quizplus · Accepted Answer

A genetic map unit, also known as a centiMorgan, is defined as the distance between two genes that results in a 1% frequency of recombination. This is a measure of genetic linkage and does not correspond to a fixed physical distance on a chromosome, as the rate of recombination can vary across different regions of the genome.
