The analyses of differences between the observed and the expected values for MC4R/NcoI genotype groups (Table II), as based on the Hardy-Weinberg law, showed that the differences were statistically significant for all color variations with the exception of the Sapphire cross.
The book touches on numerous topics, from the highly technical (such as the relevance of Hardy-Weinberg law for understanding natural selection, the importance of Hox genes for development of particular organisms) to the rather speculative (such as the would-be implications of Darwinism for fatalism or the philosophical problem of evil).
He begins with genetic variation, describing the Hardy-Weinberg law, and variation in Drosopila.
