Sobre el origen ontogénico del ser humano: La solución científica
Every living being is the result of a genome-environment interaction. Neither human oocytes nor spermatozoids have human functional genomes, but the zygote that they constitute may have a human functional genome and other functional genomes such as those of the hydatidiform mole, polyploids, and non...

Every living being is the result of a genome-environment interaction. Neither human oocytes nor spermatozoids have human functional genomes, but the zygote that they constitute may have a human functional genome and other functional genomes such as those of the hydatidiform mole, polyploids, and non-human living beings.
