All right now we're going to be talking about some diacotomous traits within humans, and then talking a little bit about mendel's experiments and some of the various outcomes they might have had.
00:17
So first let's talk about two traits.
00:20
So that's not what i wanted.
00:22
So there's so there.
00:25
So some two traits that are dichotomous in humans are.
00:32
One going to be the cleft chin or the absence thereof.
00:41
The cleft chin is going to be whenever you have that line run in parallel.
00:50
See your face alongside.
00:51
Right up your chin.
00:53
That's going to be a dominant trait.
00:55
And then the absence of the cleft chin is going to be a recessive trait.
01:00
If neither parents have a cleft chin, then you're not going to have a cleft chin.
01:06
Because if they do have a clft chin, it means that they have the trait.
01:08
At least one copy of it.
01:11
And two, the second trait we're going to be talking about, is going to be free or attached earlobes.
01:19
Basically, if you go in you, look at your ears.
01:22
The little dangly part of your ear that's like just all skin and fat down to the very bottom of your ear.
01:30
If it goes straight to attach to the side of your face, then it is attached and it's a recessive trait.
01:43
Let's see.
01:45
And then if it goes back up a little bit and then attaches, then you have a free earlobe such that you can actually move it without it pulling at the attachment.
01:57
Like forward and backward without there being a direct attachment right there.
02:01
So we'll go ahead and...
02:10
Attachment.
02:19
But yeah, so those are going to be the few traits that are within humans and are dichotinous traits.
02:25
Next, what are the pros and cons of experimenting with these traits in the way that mendel did? so pros and cons.
02:41
So pros, it's easy.
02:47
Basically, if you only have two traits to look for, the counting's easy.
02:56
It's not as hard to get a good number of data points so that you have statistical significance...
