The question that is given over here, it says that a man and a woman, they have five children.
00:21
Then we have to find the probability of this couple having four unaffected and one affected child if both the parents are carrier.
00:35
Basically, sickle cell diseases like the isical cell anemia.
00:48
These are genetic disorders of blood or disease.
00:55
Individuals with these sickle cell conditions have abnormal genes and mostly these genes are autosomal resistant and they produce an abnormal hemoglobin which is called as the hbs instead of hbea.
01:24
So this is the normal one.
01:27
These hbss, it causes the episodes of sickling.
01:31
So let us take a look on the representation.
01:35
Let hba, hba, this be the normal or unaffected one, and then hba and hba this be the carrier, hbs, be the affected one.
02:14
So what we are going to do? we are going to cross two carrier that is hba hbs is crossed with hba hbs...
