Tay-Sachs disease is inherited as an autosomal recessive trait and is lethal in the homozygous recessive condition at the age of 2years. A heterozygote marries a genotypically normal individual. What is the probability of having children that have Tay-Sachs?

1. A severe disease that is inherited as an autosomal recessive trait is more likely to skip generations in a pedigree than an autosomal recessive trait that cuases a harmless phenotypic variant because a) all autosomal recessive traits skip generations b) a person with the harmless variant is less likely to reproduce than a person with the disease c) a person with an autosomal recessive disease is less likely to be well enough to reproduce than a person with a...

Tay Sachs is an autosomal recessive disease's leading to nerve cell damage and early childhood death. 1 in 250 humans are carriers. There is NO BENEFIT to being a carrier for this disease. Since there is no benefit, list the hardy Weinberg assumptions in order of likely reasons that this disease is so widespread AND describe why you piked this order. (no more than 1-2 sentences each)

HUNTINGTON’S DISEASE is an autosomal dominantly inherited, degenerative human disease of the nervous system. Individuals homozygous for this dominant gene almost always die as a fetus. The disease has no obvious phenotypic effects in a heterozygous individual, until a person is about 35-40 years old, well into child-rearing years. There is no known cure for this genetic disease. E. Determine the results of a mating between two parents, both of whom will get Huntington’s disease. Provide the Punnett square and...

Suppose colourblindness is an X-linked recessive trait, while Huntington's disease is an autosomal dominant trait. Assume both traits are rare. A colourblind man decides to have children with a women who is heterozygous for both genes. What is the probability that they will have a child that is colourblind and does not have Huntington's?

Albinism is a rare autosomal recessive trait in which there is a complete absence of melanin pigment in the skin, eyes, and hair. A normally pigmented woman whose parents are normal has a brother who is albino. She marries a normally pigmented man whose grandfather was albino. What is the probability their first child will be albino? I would like to see the problem worked out. Dont understand why it is 1/12. Thank you in advance
