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.
The genetic distances between the three genes (genes AB, CD, and EF) were identified using a two-point mapping cross. Given the following distances, what is the sequence of the three genes in the chromosome?

20 cze 2023 · Design a series of crosses to determine the map distance between these two loci. You can start with any genotypes you want, but be sure to specify the phenotypes of individuals at each stage of the process.
Genes A, B, G, and H are located on the same chromosome. The distances between the genes are below:
A genetic map (or recombination map) is a representation of the linear order of genes (or loci), and their relative distances determined by crossover frequency, along a chromosome. The fact that such linear maps can be constructed supports the concept of genes being arranged in a fixed, linear order along a single duplex of DNA for each chromosome.
The idea of genetic linkage is the basis for a genetic map. This idea states that if there is a _____ distance between two linked genes on a chromosome, there is a _____ chance that those two genes will be inherited together.
