Step by step
Solved in 2 steps
- Sickle cell anemia is inherited as an autosomal recessive condition. It also exhibits incomplete dominance in that the heterozygous genotype displays a mild form of the disease known as sickle cell trait while individuals with the homozygous recessive genotype have a severe form of SCA. A man who has severe sickle cell anemia marries a woman who suffers from a mild trait. What is the probabilitu they will have a child with severe SCA?What is the probability they will have a child with mild SCA? What is the probability they will have a normal child? Show ALL work using punnett squares.Can a male be a carrier of red-green color blindness?The autosomal (not X-linked) gene for brachydactyly, short fingers, is dominant to normal finger length.

What is the probability that their first child will be a brachydactylous girl? ¼ 1/2 1/8 3/4 2/3
- A homozygous mother has retinoblastoma, a dominant sex-linked disorder carried on the X chromosome. The father does not have this disorder. What is the chance they will have a child with this disorder? 1) 0% 2) 25% 3) 50% 4) 75% 5) 100% 身Hemophilia is a sex-linked trait where XH gives normal blood clotting and is dominant to the hemophilia allele X h Identify the genotypes of… 1) a woman with normal blood clotting whose father had hemophilia 2) a normal man whose father had hemophilia. What is the probability that a mating between these two individuals will produce a child, regardless of sex, that has hemophilia?An individual with 46, XX genotype is diagnosed with Duchenne-type Muscular Dystrophy, a recessive X-linked disorder.

Explain how this could happen.A patient has two parents with Huntington's disease. They may not have inherited this autosomal dominant disorder due to: 1) increased DNA repeats (CAG) during spermatogenesis 2) incomplete penetrance 3) inheriting one recessive alleleIf the cow that is heterozygous for citrullinemia is inseminated by bull that is homozygous dominant, what is the probability that a calf inherits citrullinemia?
