Question
Mendelian Genetics & Punnett Square Practice Problems 1. The ABO blood group has two codominant alleles. A and B, anonrecessive allele, O. If a mother has type A blood and her child has type O blood, can a man with type B blood be the father? (hint: Remember that O the possible genotypes for the mother, the child, and the possible father.) is recessive, so consider all 2. If a child is blood type AB and the mother is blood type B, which of the following men could be the father of the child? Father #1-blood type Father #2-blood type B Father #3-blood type A Father #4-blood type AB Dimples (D) are dominant to no dimples (d) and a Widow's peak (W) is dominant to a straight hairline (w). What are the resulting genotypes and phenotypes of the following cross? 3. Person who is homozygous for dimples, heterozygous for Widow's peak crossed with a person who is homozygous for no dimples and homozygous for a straight hairline.Explanation / Answer
1. Yes. For a child with O group for mother of B group, father can be B or A or O.
2. Father #3- blood type A or Father #4- blood type AB is possible in given scenario.
