Honey bees have very large crossover costs and you may lowest low-crossover prices

Inside the per colony, we become mosaic drone chromosomes having genotype changing in one haplotype to another of your own king (Shape 1B; Contour S2B and Contour S4 into the Additional file step one), that are the result of COs otherwise gene sales. Once filtering these possible non-allelic sequence alignments, the brand new genotype changing circumstances was basically thought of along side chromosomes to identify new CO or gene transformation events. While the nearly all personally seen gene sales in other taxa enjoys region lengths notably less than just ten kb [8,45], i assume that the brand new covers that have >ten kb is an outcome of COs. When the spans below 10 kb which have the same genotype produced by one of several a couple of haplotypes of king was assumed in order to end up being the result of gene sales (including crossover-related gene conversion rates and low-crossover gene sales), when you’re spans >10 kb are believed become COs, all in all, 3,505 COs and you may 250 gene conversion process events was in fact recognized in the 43 drones (they have been the websites out-of multiple COs on the highest gaps, More file cuatro). Ones 250 gene conversions almost all (221) commonly during the proximity to help you CO occurrences and you may suggest, we imagine, NCO situations. Considering a beneficial genome out-of proportions 220 Mb (joint length of make chromosomes), that have an average of 81.5 COs for every genome, we estimate a good CO rate of 37 cM/Mb and you can 5 to 6 NCO gene sales for each drone for every single meiosis (Desk step 1 and you may Desk S4 within the Additional file dos). NCO situations inside the pit places could not be perceived if you are CO events inside the gap regions in theory can sometimes be seen. Considering a good 9.04% pit in the genome, the genuine level of NCOs could well be 9.04% large, that it becoming a correction.

I remember that relaxing brand new 10 kb presumption with the span to help you define whether or not a great recombination system might be recognized as gene conversion or crossover renders little to no differences (Extra document 1: Contour S5). 86 and you can , respectively); whenever we suppose gene conversion process tracts are going to be doing 20 kb the fresh equivalent number handle to six.21 in the place of . Ergo the new discovering that very recombination situations try crossovers and you can NCO gene transformation is apparently uncommon is robust to the ten kb presumption. It mostly shows that rareness out-of recombination events regarding step 1 so you’re able to 20 kb assortment, affirmed if gene transformation is uncommon and tracts was short. Furthermore even in the event we’re ‘far more generous’ so you’re able to gene sales situations, improving the cutoff worth so you’re able to one hundred kb, we get well simply 10.step three gene conversion rates each drone and you will 72.5 crossovers each drone. Once the our strategy are going to be robust so you’re able to figuring NCO gene conversion process pricing, these figures, and that take each other NCO and unusual cutting-edge CO associated gene sales, was liberal quotes of the NCO gene rate of conversion (offered restrictions enforced by marker occurrence). An evidently reasonable NCO gene rate of conversion for this reason appears to be a powerful completion.

If we impose a higher maximum getting gene sales of 1 kb then your level of gene conversions (each other NCO and you may CO-associated) decreases a tiny bit and also the CO rates rises (so you can cuatro

An implicit presumption i build is the fact that recombination speed counted inside the drones was reflective of these knowledgeable by the genetics carried so you can gurus. As meiosis takes place just before employee/drone specification, a good priori we expect one to genes from inside the gurus and you can drones to help you have observed the same recombination price. This might be in fact the outcome. We discover sampling six professionals off nest III (Tips for facts) that the quantity of crossover occurrences for the for every single haplotype (82.0 ± 8.6, regarding the listing of 69 to help you 90; Desk S1 into the Even more file dos) is no unlike one to witnessed during the drones (two-tailed Brunner-Munzel test, P = 0.90).
