Zoology - Principles of Inheritance and Variation Question with Solution | TestHub

The tendency of genes present on the same chromosome to be inherited together is called linkage. All the genes on a chromosome are said to be linked to one another and belong to the same linkage group. The number of linkage groups of a particular species corresponds to its haploid number of chromosomes or number of pairs of chromosomes.Drosophila has 8 chromosomes thus it has four linkage groups whilePisumhas 14 chromosomes thus it has seven linkage groups.
