Among the largest ejaculates relative to body size belongs to the boar Sus scrofa. And each litter can have anywhere from one to eight kittens! To make sure this order happens the right way, genes get turned on and off in different amounts and in a very specific order by things called transcription factors. But the 2018 study authors warned that their results didnt account for other factors that affect sperm production, such as type of pants or what fabric undies are made of. Even stripping off the eggs outer layer doesnt really help. Then, inject them into the bloodstream of a second embryo. The offspring of such a union would be half-ape, not half-monkey.

When genes are turned on and off has a lot to do with why we cant make Mogs. Ethical considerations preclude definitive research on the subject, but its safe to say that human DNA has become so different from that of other animals that interbreeding would likely be impossible.

Dog genomes tell dogs to have four legs, fur and tails. The first includes all those factorscalled pre-zygotic reproductive isolating mechanismsthat would make fertilization impossible.
