Electron microscopic analysis of the banding pattern in the salivary gland chromosomes of Drosophila melanogaster. Divisions 11 through 20 of X.

abstract：:The association between recombination rate and diversity, but not divergence is considered to be driven mainly by natural selection: fixation of positively selected variants and associated hitchhiking effects and/or background selection eliminating deleterious alleles. In the present study, we investigated the relatio...
