in humans, the abo blood type is under the control of autosomal multiple alleles. color blindness is a recessive x-linked trait.mom is type a and has normal color vision. dad is type a and has normal vision. they have a son who is type o and is color-blind. what is the probability that their next child will be a daughter who is type o and has normal color vision?

Verified Answer :

Color blindness and blood type are independent with each other. To answer the problem we have to calculate the probability of both traits. We calculate as follows:
P(Normal vision) P(blood type O)   P(girl baby)  = (1)(1/4)(1/2) = 1/8 

Hope this answers the question. Have a nice day.
