1.In humans, there is a disease called Phenylketonuria (PKU), which is caused by a recessive allele. People with this allele have a defective enzyme and cannot break down the amino acid phenylalanine. The disease can cause mental retardation or death. Let "E" represent the normal enzyme. Also in humans, in a condition called galactose intolerance, or galactosemia, which is also caused by a recessive allele. Let "G" represent the normal allele for galactose digestion. In both diseases, normal dominantes over recessive. If two adults were heterozygous for both traits, what are the chances of having a child that is completely normal? Has just PKU? Has just galactosemia? Has both diseases?
2. In the 1950's, a young woman sued film star/director Charlie Chaplin for parental support of her illegitimate child. Charlie Chaplin's blood type was already on record as type AB. The mother of the child had type A and her son had type O blood.
a. Complete a Punnett square for the possible cross of Charlie and the mother
b. The judge ruled in favour of the mother and ordered Charlie Chaplin to pay child support costs of the child. Was the judge correct in his decision based on blood typing evidence? Explain why or why not.
3. Red-green colour blindness is inherited as a sex-linked recessive trait. A colour-blind man and his wife with normal colour vision have a child. The woman gives birth to a daughter who has red-green colour blindness. The man claims that he could not have fathered this daughter. Before he goes on to Maury Povich to dispute his claim, could you use genetics to find out who is the father? Explain your answer using a Punnett square
4. In snapdragons, blue flowers are incompletely dominant over red flowers and the intermediate trait appears as purple. Use Punnett squares to answer the following questions.
a. A blue flowered plant is crossed with a purpa. A blue flowered plant is crossed with a purple flowered plant. What are the phenotypes of the offspring?
b. What would be the genotypic and phenotypic ratios be if two purple flowered plants are crossed?
