Phenylketonuria is an inherited disease caused by a recessive allele. People with PKU can't break down the amino acid phenylalanine properly; this compound and a byproduct can accumulate in the blood to toxic levels, causing mental retardation. A man and a woman are both normal, but they are carriers of the disease. A) If they have children together, what proportion of the kids would be expected to have PKU? B) What proportion of their children would be normal?

11. A boy, whose parents and grandparents had normal vision, is color-blind. What are the genotypes for his mother and his maternal grandparents? Use XB for the dominant normal condition and Xb for the recessive, color-blind phenotype 12. In humans, sickle cell anemia is a disease caused by a mutation of a single locus gene which codes for an important blood protein. The allele for the normal protein (S) is dominant to that for the one causing sickle cell anemia....

With typical cystic fibrous, the condition is caused by a single recessive allele. If a woman and her husband are both carriers and produce three children, how likely is it that: A)All 3 children do NOT have cystic fibrous (not the trait)? B) One or more children will have the disease? Please include legends and punnet squares. SHOW THE WORK so I can finally understand this! Thanks.

5. (30 0 points) Phenylketonuria (fen-ul-ke-toe-NU-re-uh), also called PKU, is a rare inherited disorder that causes an amino acid called phenylalanine to build up in your body. PKU is caused by a defect in the gene that helps create the enzyme needed to break down phenylalanine. Without the enzyme necessary to process phenylalanine, a dangerous buildup can develop when a person with PKU eats foods that are high in protein. This can eventually lead to serious health problems. For the...
