29 cze 2024 · The pairwise map distances for four linked genes are as follows: A-B = 28 m.u., B-C = 15 m.u., C-D = 25 m.u., B-D = 10 m.u., A-D = 38 m.u., A-C = 13 m.u. What is the order of these four genes?
Suppose that the distance between two genes on a linkage map is 7 units. The cross-over frequency between the two genes is
By finding recombination frequencies for many gene pairs, we can make linkage maps that show the order and relative distances of the genes on the chromosome.
Calculate the map distance between loci given the phenotypes of offspring or predict phenotypes of offspring given the recombination frequency between loci. Use the distance to construct genetic maps based on data from two-point or three-point testcrosses.
A genetic map shows the map distance, in cM, that separates any two loci, and the position of these loci relative to all other mapped loci. The genetic map distance is roughly proportional to the physical distance, i.e., the amount of DNA between two loci.
