Question
Paternity Testing Questions A woman is pregnant and wants to identify the father of her child. She admits "going wild" one night with a group of her male friends, and doesn't remember some of the details of that night. She believes there are three men who might be the father. The table below gives you everyone's genotypes for these 6 genes-i.e., the table tells you which alleles the person has for each of these 6 genes. Each genotype has two alleles in it, because we all have two copies of each of these 6 genes. Do the data implicate any of these three men as the true father of the child? Give me an explanation of why you do or do not identify Man1, Man2 and Man 3 as the father of the child. Give a specific answer for each man, identifying the genes whose data do not implicate any man who is not implicated as the true father of the child.Explanation / Answer
The interference can be drawn by applying the principle that the child's genotype must be a combination of parent's genotype in all the genes concerned.
Gene 1 implies that Man 3 can't be the father as A,G(mother) and A,T(man 3) won't be able to produce a baby with A,C.
Gene 2 implies implies the same that Man 3 can't be the father.
Gene 3 implies both Man 2 and Man 3 can't be the father as none of them has T allele present in the baby.
Gene 4 also implies that Man 2 can't be the father.
Gene 5 implies neither man 1 nor man 2 is father as none of them has C allele found in baby.
Gene 6 implies that Man 2 and Man 3 can't be the father.
So, none of the men is the true father of the child.
