From: Monogamy and high relatedness do not preferentially favor the evolution of cooperation
Effect of indirect fitness and kinship on helping. When helpers are randomly redistributed across nests, the frequencies of A after 500 generations are not above levels due to mutation rate for any level of expected survival of adults between cohorts. Helping is either dominant (green lines: darkest = 1 father, lightest = 5 fathers) or recessive (blue). Each point represents the mean of 100 individual simulations.
