> If you think this is not reasonable remember when you only have one kind
of sex allele you get a male and when you have two different sex alleles
you get a female.
A single activated gene (such as the sex determination gene) can start off
a regulatory cascade (such as that initiated by the then-activated gene
feminize). That cascade can again have forks activated by a different gene
or genes, or as in the case of female bees, epigenetic regulation, due to
environmental factors, such as how they are fed as larvae.
