But even epigenetics does not cover all of the ways that derived traits can be passed. For instance, prenatal testosterone levels affect the baby [0], yet those same levels may be affected by the mother's environment. Hence the environment may have effect on lifespring through means other than just epigenetics.

- toasterlovin 9y agoPrenatal testosterone can alter the baby's phenotype, but can it alter the baby's genotype? Something has to alter the baby's genotype (more specifically, the genes in germ line cells, which are the only cells whose genetic material gets passed on to offspring) in order to count as a method of heritability. Otherwise prenatal testosterone is the same as any other thing in the environment which can alter an organism's phenotype.
