Question

male and female, male blood group is AB and female blood group is A do crossing and find ratio of genotype and also find all condition which are generate. please give me answer fastly.​

Answer 1

Answer:

Blood group of male parent = AB

Blood group of female parent = A

Now, the genotype of female's blood group can be either heterozygous or homozygous.

If it is heterozygous the genotype will be $\tt{I^AI}$.

And if it is homozygous the genotype will be $\tt{I^AI^A}$.

If the female parent with the heterozygous blood group A crosses with male's blood group AB, then the progeny produced will be :- $\tt{I^AI^A}$, $\tt{I^AI^B}$, $\tt{I^AI}$ and $\tt{I^BI}$. That means the progeny can have blood group A, AB and B. Here, the genotypic ratio can not be determined because all of them have different genotypes. The phenotypic ratio can be 2:1:1 as two of them have blood group A.

Now, considering that the female parent with homozygous blood group A crosses with male's blood group AB, then the progeny produced will be :- $\tt{I^AI^A}$, $\tt{I^AI^B}$, $\tt{I^AI^A}$ and $\tt{I^AI^B}$. That means, there is 50% chance of the blood group A in the progeny and 50% chance of the blood group AB in the progeny. The ratio of genotype will be 1:1 and the phenotypic ratio will be same that is 1:1.
