"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. Let’s apply this idea to our test cross data. " - Chromosome map units

WebA) Individuals inherit particular chromosomes attached to genes. B) Mendelian genes are at specific loci on the chromosome and, in turn, segregate during meiosis. C) No more than a single pair of chromosomes can be found in a healthy normal cell. D) Natural selection acts on certain chromosome arrays rather than on genes. Answer: B 3 WebSep 12, 2024 · In genetics, a centimorgan (abbreviated cM) or map unit (m.u.) is a unit for measuring genetic linkage.
