What are three ways to determine if an observed disease phenotype is inherited?
6. Hemochromatosis is an inherited disease caused by a recessive allele. If a woman and her husband, who are both carriers, have three children, what is the probability of each of the following? (a) All three children are of normal phenotype. (b) One or more of the three children have the disease. (c) All three children have the disease. (d) At least one child is phenotypically normal. (Note: It will help to remember that the probabilities of all possible outcomes...
What is the value of knowing if a disease is inherited or environmental?
Explain three ways the body is protected from disease.
hemophilia is inherited as an Xlinked recessive mutation. Tay Sachs disease (ts) is inherited as an autosomal recessive. A hemophilic man is heterozygous for the ts allele . what fraction of his sperm will carry the recessive ts allele and hemophilia allele together ?
Explain three ways that diabetes can contribute to heart disease
Human disease can result from infection by pathogens, environmental conditions, and/or it can be inherited from the parents (i.e. genetics). You are working for the Center for Disease Control and you have been assigned to determine if a new disease results from a pathogen, an environmental condition, or genetics. With what you know right now, how would you determine that the disease is in fact a genetic disorder?
Discuss the three ways by which a disease present in the mother may be passed to the fetus or newborn infant.
Imagine that a newly discovered, recessively inherited disease is expressed only in individuals with type O blood, although the disease and blood group are independently inherited. A normal man with type A blood and a normal woman with type B blood have already had one child with the disease. The woman is now pregnant for a second time. What is the probability that the second child will also have the disease? Assume that both parents are heterozygous for the gene...
Consider the disease cystic fibrosis, which is inherited as an autosomal recessive trait.a. An unaffected male and unaffected female have an affected child. What is the probability (in %) that the next three children will be affected? Your answer will include two significant digits after rounding (i.e #.#). Don't include the % sign!b. What is the probability (in %) that the next three children (after the birth of the first affected child) will be unaffected males? Your answer will include...
3.2.3 Suppose that a disease is inherited via a sex-linked mode of inheritance, so that a male offspring has a 50% chance of inheriting the disease, but a female offspring has no chance of inheriting the disease. Further suppose that 51.3% of births are male. What is the probability that a randomly chosen child will be affected by the disease?
