Now, when I went to school a long time ago, we were taught that men have these chromosomes and women have these chromosomes and that was it. And most people still think that way, but what we now know, through advancements in science, is the human race can have a combination of up to 42 different sets of chromosomes.
That is astonishing. Were they really taught that? Because when I was in school (some 40 years ago), we were taught that humans have 23 pairs of chromosomes, only one pair of which is involved in determining sex.
Does anyone else have a very strong suspicion that the Mermaids person doesn't know what chromosomes are, or what they do?
