Martin and Sue are contemplating having children, but Martin’s brother has an autosomal recessive disease and Sue’s great-grandmother also had the same disease. Sue has a sister who has three normal, healthy children. What is the probability that Martin and Sue’s first child will have the autosomal recessive disease? HINT draws out pedigree charts and punnett squares for Martin and Sue.

The following pedigree shows the pattern of inheritance of red-green color blindness in a family. Females are shown as circles and males as squares; the squares or circles of individuals affected by the trait are filled in black. What is the chance that a son of the third-generation female indicated by the arrow will be color blind if the father is not color blind? If he is color blind?
Duchenne muscular dystrophy is a sex-linked recessive disorder characterized by a progressive loss of muscle tissue. Neither Carla nor Rudy has Duchenne muscular dystrophy, but their first son does have it. What can you say about Rudy's or Carla's genotype in relation with the disorder? If the couple has a second child, what is the probability that he or she will also have the disease? Show your answers with a Punnet square.

Two normal parents have a child with cyatic fibrosis. Would this be an autosomal dominant or autosomal recessive disorder? What is the chance that their next child will have cystic fibrosis?
Cystic fibrosis is a genetic disorder that results in the build-up of thick mucus in the lungs and pancreas causing serious respiratory and digestive problems. It is inherited as an autosomal recessive disease. If two individuals heterozygous for cystic fibrosis marry, what is the probability of them having three children consecutively with this disorder? Using punnett square, show ALL work done to achieve your answer.
Bryan has albinism, an autosomal recessive trait, which means he is homozygous recessive for albinism and his genotype is aa. Bryan's parents, Frank and Amy, do not have albinism however they must both be heterozygous. Bryan's sister, Allice, is a carrier for albinism. If Allice has offspring with Jim, who has no family history of albinism, what are the chances that their offspring are carriers for albinism? What are the chances that they children will get albinism? Use Punnett squares.
