Answer #1

Answer:

a). 1/8

Explanation:

Based on the information, the followings are the genotypes of parents.

Tim (IBIO; Rh+Rh-) x Tina (IAIO; Rh-Rh-)---- parents

IAIO x IBIO = IAIO (A-1/4), IBIO (B-1/4), IAIB (AB-1/4)& IOIO(O-1/4)

Rh+Rh- x Rh-Rh- = Rh+Rh-(1/2)&Rh-Rh-(1/2)

Chance of O negative = IOIO; Rh-Rh- = 1/4*1/2= 1/8

B). 1/64

Explanation:

The frequency of any blood type =1/8

Therefore, ..

the chance that if they have two children that they will have the same blood type = 1/8*1/8=1/64

    how to solve on excel? i do not have minitab 4. The blood type O negative is called the "universal donor" type, because it is the only blood type that may safely be transfused into any person. Therefore, when someone needs a transfusion in an emergency and their blood type cannot be determined, they are given type O negative blood. For this reason, donors with this blood type are crucial to blood banks. Unfortunately, this blood type is fairly rare;...
