Standard deviation

Group 3

Simple deflection

So diploid just means it has its full complement of chromosomes, so it has 2N chromosomes.

Sample standard deviation

Chimpanzees have two sets of 24, or 24 pairs of chromosomes.

Two chromosomes.

It has two chromosomes.

Fruit flies have 4 pairs, and bananas have 11 pairs.

We each have 23 pairs of chromosomes.

So let me draw some chromosomes.

We have astigmatisms. It degenerates over time.

Before every somatic cell division, chromosomes are duplicated so that each daughter cell receives an identical set of chromosomes.

And we'll come back to chromosomes in a minute.

So S, you have replication of your chromosomes.

It now has four chromosomes.

And then you have these two other special chromosomes.

Cows have 30 pairs of chromosomes.

Chickens have 39 pairs.

So the empirical rule tells us that this middle area between one standard deviation to the left and one standard deviation to the right, that right there is 68 .

So I'll draw my father's chromosomes in blue.

Then I have 23 chromosomes from my mother.

And on these chromosomes are roughly 25,000 genes.

So you still have a diploid number of chromosomes.

It's actually whole chromosomes determine it.

different species have different numbers of chromosomes.

Rhesus monkeys have 21 pairs of chromosomes.

The war on terror is an aberration.

Put away from yourself a perverse mouth. Put corrupt lips far from you.

Put away from thee a froward mouth, and perverse lips put far from thee.

If they're slightly skewed, we'll see a different image.

One standard deviation to the left is going to be minus 1.

He's absolutely harmless except for one small mental quirk

Engine seals check. Oh, God. Oh!

Testing, testing. One, two, three, four.

All act in the same way during cell division.

It is obviously central to the movement of the chromosomes.

Let's see, so I have 23 chromosomes from my mother.

Human cells have 23 pairs of chromosomes.

It's got 2N chromosomes, and then it grows.

As it goes through S phase, these chromosomes replicate.

And you have your two chromosomes in this case.

And so we started down the road of can we synthesize a chromosome?

I can just keep going. And eventually you have 22 pairs.
