So when we think about blood type, we have to think about codominence.
00:06
So what that means is that there are two alleles, like in a heterozygous, so in this case being a and b, that even though you have two alleles, you would expect one to be dominant over the other, but codominance means that they're both showing, and they're kind of like fighting for that dominant position.
00:30
So when someone has an ab blood type, that means that they're showing both the trait of a and the trait of b.
00:39
So that's one of the things we have to think about when we think about codominance.
00:43
And i'm sorry, when we think about blood type.
00:46
Another thing that we have to think about that a lot of people don't realize is we have to think about this concept called, oh, i did not delete like i wanted to do.
00:56
Multiple alleles.
00:58
So multiple alleles is kind of extinct.

What it sounds like...
