09 mai What can cause the newest super-higher crossing-more than rates in the societal hymenoptera
Because factors that cause brand new higher recombination speed when you look at the societal insects are unresolved, several alternatives had been omitted [2,3], rather one: (1) this isn't an effective de- facto result of haplodiploidy just like the asocial Nasonia has actually far lower costs within step 1.4 to at least one.5 cM/Mb ; and you may (2) that isn't only through domestication, because the undomesticated public wasps and you can ants also provide large prices. Furthermore there is absolutely no research into regular society genetical domestication fingerprints inside the honey bee, which possibly thanks to this new regular admixture of the treated honey bee . Because of the removing, the high crossing-more speed is apparently property of eusociality. I consider two hypotheses, just what tends to be known as resistant-mode hypothesis and also the staff diversity hypothesis, both of and this propose a good coupling between eusociality and you will high crossing-more than prices. The latest site of your own evaluation of them hypotheses is that choices having a given form will be subsequently have the ability to establish and therefore genetics have surprisingly highest crossing-more cost in their proximity [18,19].
Instance an explanation to possess increased crossover pricing wil attract because of the high human anatomy out of evidence recommending a prospective coupling between your advancement off sex and recombination and you will server-parasite co-advancement
New protected-setting hypothesis supposes a connection with enhanced immune demands away from societal types . Societal varieties can be such as for example at risk of infectious state courtesy on top of other things: (1) bodily distance, and then make transmission much easier; (2) personal relatedness, making sure here becoming of several insecure someone up close; and you will (3) because of increased heat of this societal species [21,22].
