User blog comment:BannedLagiacrus/Discussion of the Week: Monster Mutations/@comment-3277384-20140429075949

Actually in biology ALL subspecies were mutations of the original ancestor, and in MH ALL mutations are in fact true subspecies.

Once the mutation occurs, the affected specimen will mate and give to birth new monsters with that mutation, and then a new subspecies is born.

Also I don't think that all of these make sense. From what I remember, so I'm not sure, the genome of a son creature is a mix of the perfect genome of the father and the mother. Sperm and... the female egg that I don't remember how to say it in english... But the genome contained in sperm and in the egg is IDENTICAL to the genome of the sperm-bearer, and the genome don't change with years. So the genome in sperm is the one that the specimen had while having birth. So, if I eat too much carrots and I become orange, my son won't be orange. This is just a theory, now, like I said before, I don't remeber correctly all the rules of evolutive biology, maybe an unusal diet can mutate the genome of the son while still in the egg, but I don't know at the moment.
