Question

Quizplus · Accepted Answer

The positions of genes on a genetic map are marked according to minutes. A minute is a unit of measurement used in genetics, which indicates the distance between genes. One minute corresponds to 1% recombination between two genes on a chromosome. Therefore, genetic maps are constructed based on the frequency of recombination between genes as determined by genetic crosses.
