Asexual, male, female type of ancestor. two males will not reproduce a female. 2 females won't create male, 2 asexual body types will reproduce ancestors with both genitalia.
Simple compounding chromosomes rule of 128, 64, 32, 16, 8, 4, 2, each great great great great great grandchild the product of ancestral lineages changing daily population in this atmosphere so far.
