In humans the allele coding for normal metabolism of the amino acid phenylalanine (P) is dominant over the recessive autosomal allele (p) that causes the disease phenylketonuria, or PKU. Without treatment, this disease is characterized by brain damage due to the failure of the gene to code correctly for the enzyme phenylalanine hydroxylase. If a man marries a woman and both are heterozygous for hemophilia and heterozygous for PKU, what is the chance that they will have a child afflicted by both diseases? Your response MUST include: (a): list the traits involved (example: Color: Blue- B (dominate) Green - b (recessive) -Do not use this example as this is not part of the problem (b): identify if its a monohybrid or dihybrid cross and why (use prompt above) (c): create a punnet square that represents the problem above

- In humans the allele coding for normal
metabolism of the amino acid phenylalanine (P) is dominant
over the recessive autosomal allele (p) that causes the disease phenylketonuria, or PKU. Without
treatment, this disease is characterized by brain damage due to the failure of the gene to code correctly
for the enzyme phenylalanine hydroxylase. If a man marries a woman and both are heterozygous for
hemophilia and heterozygous for PKU, what is the chance that they will have a child afflicted by
both diseases?
Your response MUST include:
(a): list the traits involved (example: Color: Blue- B (dominate) Green - b (recessive) -Do not use this example as this is not part of the problem
(b): identify if its a monohybrid or dihybrid cross and why (use prompt above)
(c): create a punnet square that represents the problem above
