So basically, in deployed organisms, chromosomes always come in pairs. And that's exactly why you have a second chromosome on the board. So in humans, even though we have 46 individual chromosomes, we actually have 23 pairs of chromosomes. And each pair of chromosomes is called a homologous pair. And we'll see what that means in just a moment. So in any homologous pair, one chromosome came from the female gamete, and the other chromosome came from the male gamete.
