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?

So, genetic maps are based on rates of recombination (physical maps are based on physical distances, which we will look at in Chapter 12). Figure 11.2.1 shows a typical genetic map, giving the relative distances between and among various genes in the moth, Bombyx.
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:
