- Homework Statement
- Colourblindness is a recessive X linked trait. A couple, who are both blood type A and with normal vision have a son who is blood type O and colourblind. What is the probability that their next child would be a daughter and with blood type O and normal vision?
- Relevant Equations
- a. 1/2
b. 1/4
c. 1/8
d. 1/16
Ans is a.
I'm getting 3/32.
P= Probability of a daughter x Probability of O blood type x Probability of Normal vision
= 1/2 x 1/4 x 3/4
= 3/32
P= Probability of a daughter x Probability of O blood type x Probability of Normal vision
= 1/2 x 1/4 x 3/4
= 3/32
