genetic map
genetic map The linear arrangement of mutable sites on a chromosome, deduced from genetic recombination experiments. The percentage of recombinants is used as a quantitative index of the distance between two gene pairs, and this distance, together with those between other gene pairs, provides a map of their arrangement on the chromosome. One ‘genetic map unit’ is defined as the distance between gene pairs for which one product of meiosis out of a hundred is recombinant (i.e. it equals a recombination frequency of 1 per cent).
