Are mistakes inevitable? Sex allocation specialization by workers can reduce the genetic information needed to assess queen mating frequency.

Abstract excerpt

Insect workers can increase their inclusive fitness by biasing colony sex allocation towards males when their mother queen is mated to multiple males and females when she is singly mated. Workers need heritable variation in odour diversity to assess queen mating frequency. Here we present a simple one-locus two-allele model, which shows that the sex ratio specialization itself will often select against rare...
