So when you're mating these two species with the horse oocyte
with 32 chromosomes and the Mountain zebra who has 32 total chromosomes.
So when I say that remember half comes from mom half comes from dad.
So their egg and sperm have half that number.
So 32 so it's 16.
So the mountain zebra sperm cell only has 16 chromosomes.
It's going to come together, line up with that horse oocyte, line up 16 chromosomes,
and then that actually leaves 16 individual
chromosomes from the horse with no, no pairing.
So, those genes that are there, that are,
that, that those genetics are, are in essence, lost.
So, that's why a lot of these hybrids fail, because you're
not getting proper you know, combination of the genes to produce offspring.
Now, we're going to talk about the, the first hybrid is
the horse and donkey hybrid, and it results in two types.
So if you mate a female horse to a male donkey or
a jack, so a mare to a jack, you get a mule.
And what's interesting is this, this is pretty successful.
So, they get a 90% ferti, fertility rate,
you know, really good fertilization rate and reproductive rate.
And that's probably why we see so many mules
in the world today, over 10 million, is because
you made them and, just, just like any other
horses, or donkeys, you know they, they have good rates.
