Causes and outcomes away from crossing-more confirmed via a leading-quality recombinational landscaping of your honey-bee

Personal hymenoptera, the honey-bee (Apis mellifera) in particular, has actually ultra-higher crossover cost and a big level of intra-genomic version from inside the crossover cost. Aligned with haploid genomics of men, this will make her or him a potential model to possess exploring the explanations and you can outcomes out of crossing over. To deal with why societal bugs has actually including large crossing-over pricing additionally the consequences from the, i constructed a top-resolution recombination atlas of the sequencing 55 folks from around three colonies with the common marker occurrence of 314 bp/marker.

Show

We discover crossing over is especially filled up with proximity so you can family genes upregulated in the employee heads, however, look for no facts having a good coupling with resistant-related performing. We find just a low rate regarding non-crossover gene conversion process, contrary to current facts. This might be inside hitting examine for the ultrahigh crossing-over rates, almost double one previously estimated off all the way down resolution investigation. We robustly recover the latest predicted intragenomic correlations between crossing over and you can each other population peak range and you may GC articles, which could be greatest explained since the secondary and you can head consequences of crossing-over, correspondingly.

Findings

All of our research is consistent with the see one to diversification out-of staff choices, but not immune means, is actually a motorist of your highest crossing-more speed for the bees. While we see each other higher assortment and you may highest GC blogs relevant with high crossing-more than prices, all of our estimate of your own low non-crossover speed demonstrates that highest low-crossover rates commonly a required consequence of higher recombination cost.
