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. WebThe chromosome map gives the exact location of genes in a chromosome. b. The order and the approximate distance between the genes can be learnt from a map. c. The map indicates the strength of the linkage between two genes and their chances of crossing over. d. The map helps in confirming genetic principles such as: i.
