If both husband and wife are known to be heterozygous for the autosomal recessive condition of albinism, what is the probability that among their four children, three will be normal and one will have albinism?
I know that each child has a 3/4 probability of being normal and 1/4 probability of having albinism. So is the answer 3/4 * 3/4 * 3/4 * 1/4? Or do you just do 3/4 * 3/4 * 3/4?

QUESTION 6 Albinism (lack of skin and hair pigmentation) is caused by a recessive autosomal allele. A woman and man both normally pigmented, have an albino child together. For this trait, what is the genotype of the albino child? O A. It is unknown, because not enough information is provided. O B. heterozygous O C. homozygous dominant OD.homozygous recessive O E. It depends on the environment that the child lives in. QUESTION 7 in...

Suppose that you are studying is a rare recessive condition in humans whereby affected individuals are unable to metabolize a sugar found in certain foods. A woman and her husband are both heterozygous for the allele causing the condition. A) If the woman is pregnant with twins and the twins are dizygotic (non-identical), what is the probability that both twins will be girls and be affected? B) What is the probability if the girl twins are identical (monozygotic) and both...

1. Nystagmus, a condition causing oscillations in eye movement, is inherited with the dominant allele N on the X chromosome. The X-linked recessive allele n does not cause Nystagmus. An immunodeficiency disorder called Chronic Granulomatous Disease (CGD) is inherited with the autosomal recessive allele g. Individuals with the autosomal dominant allele G do not have Chronic Granulomatous Disease. a. Tiffany has both Nystagmus and CGD. Her husband Todd has neither condition. Tiffany's father does not have Nystagmus. Todd's mother has...

3. Sickle-cell disease is a genetic condition caused by an autosomal recessive allele which al- fects one in every 500 African American children born in the U.S. One in every ten African Americans is a carrier for the recessive allels. Although sickle cell disease is caused by a single human gene, it is expressed through many different effects throughout the body. The presence of a recessive sickle-cell allele in humans causes the red blood cells to produce abnormal hemoglobin protein...
