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.
Mark has an autosomal recessive condition called sickle cell anemia, a serious blood disorder that is associated with painful complications. His spouse has not experienced symptoms of sickle cell anemia but their first child developed the disease. What conclusions can be drawn about the mother's genotype and the probability of having a second child with the condition? Answer Choices: A: her genotype is heterozygous and there is a 25% percent chance of having another child with the disorder B: her genotype is heterozygous and there is a 50% percent chance of having another child with the disorder C: her genotype is heterozygous and there is a 75% percent chance of having another child with the disorder D: she lacks the allele for sickle cell anemia in that she lacks symptoms of the disease. There is a 0% percent chance of having another child with the disorderMark has an autosomal recessive condition called sickle cell anemia, a serious blood disorder that is associated with…
Answer 2 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.

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.
