What is incomplete linkage of genes, indicate the reason for this phenomenon?
| March 19, 2021 | education
Incomplete linkage is a linkage in which, as a result of crossing-over, in some cells, chromosome regions are exchanged between genes A and B, and gametes Ab and aB appear, and 4 groups of phenotypes are formed in the offspring, as with free combination of genes. That is, the numerical ratio of phenotypes does not correspond to the 1: 1: 1: 1 ratio established for the dihybrid assay crosses. The cause of the violation of adhesion is crossing over in prophase 1 of meiosis.
