Genetics of natural populations; experiments on chromosomes of Drosophila pseudoobscura from different geographic regions. Global Change Biol Bioenergy. Chromosome positions for S. If the longest tiling path for a particular scaffold did not agree with its overall alignment path on the poplar chromosome, the scaffold was marked as unlocalized.

Hooper, D. Only the longest isoform of each gene was considered in the lift-over. However, the proximal causes of recombination suppression and the pace at which degeneration subsequently occurs remain unclear.

For example, recent studies of young sex chromosome systems have revealed substantial intra-specific variation in the degree of recombination suppression across populations [ 38 , 39 , 40 , 41 ], suggesting that the boundaries of recombination suppression are not fixed within a species.
