WebThis effect, which could be termed indirect kin selection, is larger for lower recombination rates (see the expression for Z* in eq. 8). The second term is the effect of indirect selection and is due to the disruptive selection at locus j, which produces local adaptation: the modifier tends to decrease in frequency because it is more often associated with the allele that is … Web10 apr. 2024 · Haplodiploidy couldn’t be the driving force underlying the evolution of those insects’ eusociality.

We show that our model can be interpreted in two ways, as either altruism within species, or altruism between species.
