(3 points) what is John's genotype for AB rh minus blood typc c. (2 points) What is the probability that Monica and John blood type? onica and John wll have a child with AB Rh negative ld with A Rh positive d. (2 points) What is the probability that Monica and John will have a ch blood type? e. (2 blood type? points) What is the probability that Monica and John will have a child with B Rh negative 2Explanation / Answer
a) Monica's blood type is A Rh positive, and her father's blood type is O Rh negative. This indicates that Monica is heterozygous for both the A blood type and Rh factor, hence her genotype will be IaIo Rr
b) Given that the blood group of John is AB Rh minus blood type, his genotype will be IaIb rr, since A and B blood types are co-dominant and the dominant form of gene for Rh factor is positive.
c) Monica has a genotype of IaIo Rr and her husband john has a genotype of IaIb rr, therefore any possible offspring of theirs can have any one of the following genotypes: IaIa Rr, IaIarr, IaIb Rr, IaIb rr, IaIo Rr, IaIo rr, IbIo Rr, IbIo rr.
Out of these possible genotypes, only IaIb rr genotype shows AB rh minus blood type, hence the probability of their child having AB rh minus blood type is 1 out of 8, i.e., 1/8
d) The only genotypes that can give A Rh blood type will be IaIa Rr and IaIo Rr, i.e., 2 out of 8 possible blood type will give an outcome of A Rh positive blood type, therefore the probability of Monica and John having a child with A Rh positive blood type will be 2/8 or 1/4
e) The only genotypes that can give B Rh negative blood type will be IbIo rr, 1 out of 8 possible blood type will give an outcome of B Rh negative blood type, therefore the probability of Monica and John having a child with B Rh negative blood type will be 1/8
