A couple has two children with blood groups LMLM and LNLN.
a) What are the genotypes and phenotypes of the parents?
b) Using a punnet square, work out the genotypic and phenotypic ratio of the offspring of these parents using your answer to part a) above.
c) Two individuals with the blood groups AB (mother) and B (father) have a child with type A blood group. The father denies fatherhood of the child. Does the evidence of the baby’s blood type support the man’s claims? Why?
