Due to selective mortality, maternally inherited Spiroplasma and Wolbachia can distort this quantity in arthropod populations.
Due to selective mortality, maternally inherited Spiroplasma and Wolbachia can distort this quantity in arthropod populations. Eric Charnov proposed that in parasitoids, this quantity varies with host size, extending the Trivers-Willard Hypothesis that it can be adjusted with maternal condition. In small populations, it may be biased by competition between siblings according to W. D. Hamilton's local mate competition hypothesis. The primary, secondary, and tertiary versions of this quantity denote its value at conception, birth, and adulthood, while its operational kind discounts non-mating individuals. Deviations in this quantity favor parents whose offspring counteract the deviation according to Fisher's principle, which explains why this ratio is often close to 1:1. For 10 points, identify this ratio of the number of the reproducing kinds in a dioecious population.
