let's say that there are two alleles.

So there's a couple of things we could do.

So these are two different alleles let me write that

We re Company C Charlie Company. There s only two of us.

And the one I drew here's one, two, three, the methyl is right over here.

No pressure, but I've got two other interested parties.

There's one, two, three, four alleles, and three of them are blue.

Now you were at those negotiating tables when they weren't, when there was maybe you one voice, maybe one or two others.

Right by twos!

Two by two. Right and left.

So it's 1, 0, 2 0, 1, 2 2, 3, 0, just like that.

0 minus 2 is minus 2.

1, 2, minus 1, 0 times minus 2 minus, minus 2. And so what would this be equal to?

Let's say that there's two people in the population, and one guy right here, his genotype is big B and

So the transformation of x2 is equal to our transformation matrix 1, 2, minus 1, 0 times 2, minus 2. And so this will be equal to 1 times 2 is 2. Plus minus 1 times minus 2.

Then upper triangular, everything below the diagonal is a 0, and everything above the diagonal probably isn't a 0, but you never know.

0 minus 2 is minus 2.

The upper triangular everything below the diagonal.

So this matrix right here.

I'm ignoring the zero because it's in the same column as the 1, 2, 0 0, 2, 3, and then 2, 0, 0.

1 minus 2 minus so it's 1 minus 2 plus minus 1 times minus 2. That's going to be plus 2.

Don't give them four, give them two plus two.

Minus 2 times minus 2 is 4.

Two!

Two.

Two.

Let's take our transformation of x2.

but he shall acknowledge the firstborn, the son of the hated, by giving him a double portion of all that he has for he is the beginning of his strength the right of the firstborn is his.

But he shall acknowledge the son of the hated for the firstborn, by giving him a double portion of all that he hath for he is the beginning of his strength the right of the firstborn is his.

So these are both A blood, so there's a 50 chance, because two of the four combinations show us an A blood type.

Everybody knows that two and two make four.

This just comes from the definition of a 2 by 2 determinant.

2 minus 2 times 1 is 0.

One, two, three, four, one, two, three, four.

So it's minus 2 plus a plus 2, so it's equal to 0.

We defined the determinant of a 2 by 2 matrix not in terms of a determinant.

0 minus 2 times 1, that's minus 2.

Two plus two equals four, and one is just one.

2 minus 2, times 1, is 0.

5 minus 2, times 2, is 1.

BOlKUTT One by one, two by two, three by three, they're wiping us out.

One two!

So I say one, two.

And you should see that is equal to 42.

Two. Separate
