WebSep 12, 2024 · In genetics, a centimorgan (abbreviated cM) or map unit (m.u.) is a unit for measuring genetic linkage. It is defined as the distance between chromosome positions (also termed loci or markers) for which the expected average number of intervening chromosomal crossovers in a single generation is 0.01. What is the map distance … WebMap units are a measure of the tendency for crossovers to occur between two loci. Because genes that are farther apart will have a higher likelihood of crossovers, the higher the crossover frequency, the farther apart the genes are on the chromosome.

"WebThese genes are distributed over a much smaller number of chromosomes: humans have 23 pairs; mice have 20 pairs, and nematode worms have six pairs in their hermaphroditic form, and 5 pairs plus one additional chromosome in their male form). As a result, many genes are linked, which means “on the same chromosome.” " - Chromosome map units
