Which of these statements about linkage groups are correct? (A) Drosophila has four linkage groups while Pisum has seven linkage groups (B) Drosophila has eight linkage groups while Pisum has fourteen linkage groups (C) Pisum has four linkage groups while Drosophila has seven linkage groups (D) Pisum has eight linkage groups while Drosophila has fourteen linkage groups

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 while Pisum has 14 chromosomes thus it has seven linkage groups.
