Infantile Tay-Sachs disease is a neurological disorder that causes a progressive deterioration of nerve cells resulting in seriously impaired mental and physical abilities. It usually results in death by the age of four. Infantile Tay-Sachs is a recessive disorder (aa) affecting 1 in 3000 individuals. (show your work) (10pts) a) What is the frequency of the "aa" genotype in this population? b) What is the frequency of the "q" allele? c) What is the frequency of the "p" allele? d)...
Use the information presented below to answer questions 6 - 8. Tay-Sachs disease is a recessive hereditary abnormality causing death within the first few years of life in individuals with the genotype tt. These individuals never reach sexual maturity. Individuals with the genotype T do not become diseased. Abnormally shortened fingers (brachyphalangy) are due to the presence of alleles in the heterozygous condition (Bb) located at a different locus. Geneticists observed that brachyphalangy was conveyed by the dominant allele and...
1. Tay-Sachs is an autosomal recessive disorder, which is the inability for infants to breakdown gangliosides in the CNS, which overtime build-up and destroy neurons. As the disease progresses, the child loses muscle control. Eventually, this leads to blindness, paralysis and death. If you have a family history of Tay-Sachs disease or if you're a member of a high-risk group and plan to have children, doctors strongly recommend genetic testing and genetic counseling. Scott and Tina are a young couple...
Two people who are “carriers” of (heterozygous) for Tay Sachs disease marry and plan a family. What is the probability that a child from this union will suffer from Tay Sachs disease. (Recall that this is an autosomal recessive disorder, that is, homozygous recessives have the disease.) a. Zero b. 0.25 c. 0.5 d. 0.75 e. 1.0 6. At Hardy-Weinberg equilibrium, heterozygotes are the most common genotype in the population when- a. b. c. d . p> 0.67 q>0.67 and...
