Completely linked genes

WebRecomb - Review. If two genes are linked, they are on the same chromosome. Because the two chromatids of the chromosomes are mirror images of each other, we can indicate linked genes like this: AB/ab, where the letters before the slash indicate the alleles on one chromatid, and the letters after the slash indicate the alleles on the other chromatid. WebLinked genes, or linkage, refer to a set of genes that tend to be inherited together because the genes are positioned close to each other on the same chromosome. ... However, the …
