- 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.

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.arrow_forward
