how many linkage groups are present in Drosophila?

A linkage group is a linearly arranged group of linked genes which are normally inherited together except for crossing over. The number of linkage groups present in an individual corresponds to the number of chromosomes in its one genome. Fruit-fly Droso­phila melanogaster has four linkage groups (4 pairs of chromosomes).
