This question is talk about inheritance.
00:03
Here you have for the most likely mode of inheritance for the area completely penetrant.
00:08
Trade is playing in this pedigree, how many individuals are heterosophiles for sure? it means 100 % probability.
00:14
So here, as you can see here, only males are affected.
00:18
And you see that affected males or disaffected people have normal parents.
00:23
When you see this, this is either an excellent recessive disorder or an autosomal, a disorder because it would mean that at least one of these parents is a cower.
00:32
It means a person who has, or who carries a mutant allele, but that does not express a disease, and that occurs in excessive disorders.
00:40
So in this case, and also in dominant disorders, you don't have coverage because of the cause.
00:44
You have at least one mutant allele in dominant diseases, you don't express a disease.
00:50
So in this case, for example, one of these parents should have a disease in order to transmit a disease here and here and in order to be a dominant disorder.
01:00
Okay? so this is either autosomal recessive or excelling recessive.
01:04
So one key information here is that this disease is rare.
01:09
Okay, it's weird.
01:10
So it means that both or that all the people that are coming out from this family are considered normal.
01:16
For example, in autosomal recessive, they are going to be like this.
01:21
It means they are not going to be, they are not going to be caggers.
01:24
So in this case, if this is autosomal recessive, then remember that a person is going to inherit one alien from each parent.
01:31
So in this case, in a lot of someone obsessive, this man would be homoseal obsessive.
01:35
Okay? you will have a homosyrogy obsessive here.
01:38
And as i told you, one individual inherits one allergy from each parent.
01:42
So in this case, this aggressive a should come from this mother and this a should come from this father.
01:46
So at least both of them should have aggressive ali.
01:51
So as both parents are healthy, then they are not going to be homosayoeoeoeoecious.
01:56
But heterocyte, but heterocycores, okay? but it would mean that this man coming from outside of family social acabble.
02:07
So as this question says that this is a rare disease, then it means that this man here is not a cover, but homocybolysm dominant, and if this man is homozygous dominant, then it means that, well, you know, this is not going to be able to fit because you need a heterocylus here.
02:25
So this is not an autosomal recessive, but this is an excellent possessive.
02:30
And also you can see that this is an excellent recessive because only males are affected.
02:36
Okay, and when you see a pedigree where males are more affected than females, then this is going to be very likely to be an excellent recessive...
