Give nine examples of lethal alleles in humans, other animals, and plants and a brief molecular explanation (i.e., why are they lethal).
Using the rule of 1500, what is a more precise rate? (hint: divide 1500 by number of small boxes)
Can someone tell me if the answer is 50% or 25%?

- The most common CF mutation is AF508; it accounts for approximately 70% of all mutant CFTR alleles worldwide. For a couple of northern European origin, what is their risk for having an affected child if each tests negative for AF508? If one tests positive and the other tests negative for AF508?arrow_forwardCystic fibrosis in humans is caused by a recessive allele. A man is known to be a carrier of the cystic fibrosis allele. He marries a phenotypically normal woman. In the general population, the incidence of cystic fibrosis at birth is approximately 1 in 1,700. Assume Hardy-Weinberg proportions. What is the probability that the wife is also a carrier? Answer in decimal number only (three decimal places; example: 0.123). What is the probability that their first child will be affected? Answer in decimal number only (three decimal places; example: 0.123).arrow_forwardSickle cell anemia is a genetically inherited autosomal recessive trait in which results in a condition that there are not enough healthy red blood cells to carry oxygen throughout the body due to the production of red blood cells that are sickle shaped. The frequency of the sickle cell condition is as high as 10% in Central Africa compared to 0.5% in the United States. Calculate the frequency of the normal and carries of the sickle cell condition.arrow_forward

Individuals with PKU have two recessive alleles and have very low levels of an enzyme that is needed to properly break down proteins. If a woman and her husband are both carriers and have three children, what is the probability of each of the following? Show your math. (Hint: You can represent your probabilities as fractions or decimals, but probabilities are always between 0 and 1) 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.arrow_forwardWhat does the likelihood ratio mean?arrow_forward
