Genetic recombination

Vedclass · Answer

(D) Genetic maps,also known as linkage maps,represent the relative positions of genes on a chromosome.These maps are constructed based on the frequency of genetic recombination (crossing over) between gene loci.The distance between two genes is measured in centimorgans $(cM)$,where $1 \ cM$ corresponds to a $1\%$ frequency of recombination.Therefore,the higher the recombination frequency between two genes,the further apart they are located on the chromosome.
