Reasons and you will outcomes off crossing-over evidenced through a top resolution recombinational landscape of your own honey-bee
Background:Social hymenoptera, the newest honey bee (Apis mellifera) particularly, enjoys ultra-higher crossover prices and you can a large level of intra-genomic variation from inside the crossover cost. Lined up having haploid genomics of males, this will make her or him a possible model to own examining the grounds and you can consequences from crossing-over. To address why societal pests jaumo have such as for instance high crossing-more costs in addition to outcomes with the, i built a leading-quality recombination atlas from the sequencing 55 people from three colonies with the typical marker thickness out-of 314 bp/marker.
Results:We discover crossing over is particularly packed with distance to genetics upregulated from inside the staff brains, but get a hold of zero evidence to have an excellent coupling having protected-related operating. We locate just a decreased rate from low-crossover gene transformation, in comparison to most recent facts. That is during the striking compare to the ultrahigh crossing-more price, nearly double you to definitely in the past estimated out of lower resolution data. We robustly recover brand new predict intragenomic correlations ranging from crossing over and you will both population top range and you will GC content, which is most readily useful informed me because the indirect and you will lead effects out of crossing over, correspondingly.
Conclusions:The study try consistent with the examine you to definitely diversification away from staff member choices, not protected means, was a drivers of your own high crossing-over rate for the bees. As we discover both high variety and you can large GC blogs relevant with a high crossing-over pricing, all of our estimate of one’s lower low-crossover rates implies that highest non-crossover costs aren’t a necessary consequence of high recombination prices.
