We're going to begin by comparing heterozygous alios and homozygous alios.
00:06
So when we have homozygous alios, i'm going to abbreviate that with homo.
00:12
That means they're the same.
00:14
So it could be, let's say, little t, little t, or it could be big t, big t, but they have to be the same.
00:23
Compared to heterozygous, i'm going to abbreviate that with hetero.
00:30
They're different.
00:31
So in this case, it'd be big t, little t.
00:33
Now, when we take a look at these, we know that recessive traits are like this here, the lowercase letters, right, compared to the dominant alials capital.
00:51
So when we take a look at these here and we think of, let's say, heterogeneous people, and let's say we're trying to eliminate a certain type of disease or certain types of alials that would be some people say are bad.
01:04
What happens is if we have a bunch of hetero people, meaning they're different, guess what? you still have that recessive or that lowercase t.
01:13
So let's say we were to cross, and we're going to do just a simple punnet square here...
