TLDR
This model is used to investigate the evolutionary stability of the mechanism of sex determination found in the wood lemming which leads to a population sex ratio of three females to one male.About:

Foundations of Social Evolution
TL;DR: How could natural selection, based on the relative rates of reproduction of different individuals, favour genes that cause their bearers to expend resources to benefit their genetic competitors?

THE GROUP SELECTION CONTROVERSY: History and Current Status
TL;DR: This review attempts to place the modem concept of group selection within its historical context by examining how its development is often haphazard and unsystematic.

Sex ratio evolution under local mate competition in a parasitic wasp.
TL;DR: With many foundresses contributing to a mating population, the optimum is one-half sons, as predicted for panmictic populations by Fisher (1930), and sex ratio evolution in spatially structured populations is of special interest.

Evolution of sex ratio in structured demes
TL;DR: The structured deme model explains the evolution of altruism by the differential productivity of trait groups, in which the dispersal pool represents the deme as a whole, and the breeding group in each resource patch is a "trait group."

The Evolution of Sex
TL;DR: In this paper, the authors compared the short-term advantages of sex and recombination in a finite population with the long-term consequences of recombination and sex and showed that recombination has shortterm advantages for both sexes.

Group Selection and Kin Selection
TL;DR: It is suggested that since behaviour favours the survival of the group and not of the individual it must have evolved by a process of group selection.

Fertile XX- and XY-type females in the wood lemming Myopus schisticolor
TL;DR: Two remarkable findings are reported: the existence of two types of fertile female with different somatic sex chromosome constitutions—the orthodox female complement, XX, and the male complement, XY, and evidence for selective non-disjunction in XY females, leading to the formation of X-type egg cells only.
