Solutions

Expert Solution

Answer =

Sally is blood type AB positive and her mother was type A- and father type B+.  

Vikram is blood type B-, and his father was type B+ and mother type O -.

A) What is Sally's genotype:

IAIB

Explanation =

mother = A- genotypes = IAi

father =  B+ . genotypes = IBIB

IA i
IB IAIB ( blood tyepe AB, sally) IBi (blood type B-)
IB IAIB( blood tyepe AB, sally) IBi (blood type B-)

==================================================================================

B) What's Vikram's genotype:

vikram blood type is B-.

genotypes = IBi ( blood type B)

Explanation =

father was type B+ = genotypes IBIB

and mother type O -.= genotypes ii

IB IB
i IBi ( blood type B) IBi ( blood type B)
i IBi ( blood type B) IBi ( blood type B)

=======================================================================================

C) The genotypes and blood types (phenotypes) possible in their children.

phenotype = Sally ( AB+) X vikram (B-)

genotypes =   IAIB   IBi

children :

IA IB
IB IAIB (blood type AB +) IBIB (blood type B +)
i IAi (blood type A - ) IB i ( blood type B-)

childrens with phenotypes and genotypes are :

1. (blood type AB +) = IAIB

2. blood type B + = IBIB

3.blood type A - = IAi

4.blood type B- =  IB i
