Journal List Sci Adv v. However, ZZf individuals exhibited normal female expression of these male-biased genes fig. Jennifer A. For each species, a unique life history index was obtained by calculating the average of the body length Z score, body mass Z score and longevity Z score.
Theory predicts that populations living in either highly variable or cold climatic conditions should evolve genotypic sex determination to buffer the populations from extreme sex ratios, yet these fundamental predictions have not been tested across a wide range of taxa. A total of 17, genes fulfilled these criteria.

Sex differences in ageing in natural populations of vertebrates. Hence, all tissues, including ovaries, in sex-reversed females appear transcriptionally normal. Environmental sex determination in reptiles: ecology, evolution, and experimental design. The present study represents the most ambitious assessment to date of the link between ambient temperature and sex determination systems.
