Sex ratio for adults (ASR)
There are key effects on behavior, ecology and population dynamics, but the cause of ASRs variation is not clear.
Here, we use data from 344 species in 117 four-legged animal families to assess whether the type of genetic gender determination affects ASR.
We show that there are significantly more male-species with females-biased ASR (
Male ratio: 0. 55 ± 0. 01 (mean ± s. e. m. ))
Than a classification group with a male alien (0. 43 ± 0. 01).
Gene
The assay system explained 24% and 36% of the variation between amphibians and reptiles ASRs species.
We have considered several genetic factors that could lead to this pattern, including division-driven and gender --
Related harmful mutations, but further work is needed to quantify their effects.
Regardless of the mechanism, genetic effects
The system of determining the sex ratio of adults may have a profound impact on the population and social behavior of quadrupeds.
