2) Tay-Sachs disease is an autosomal recessive neurological disorder that is fatal in infancy. Despite its invariably lethal effect, Tay-Sachs disease occurs at very high frequency in some Central and Eastern European (Ashkenazi) Jewish populations. In certain Ashkenazi populations, 1 in 1000 infants has Tay-Sachs disease. Population biologists believe the high frequency is a consequence of genetic bottlenecks caused by pogroms (genocide) that have reduced the population multiple times in the last several hundred years. a) In the population described,...

Tay-Sachs disease is an autosomal recessive disorder. Among Ashkenazi Jews of central European ancestry about in 1/3600 children are born with Tay-Sachs disease. What is the frequency for being a carrier for Tay-Sachs in this population? A carrier does not show the trait but can pass it on to his/her offspring.

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...

16.Tay-Sachs is an autosomal recessive disease. A couple (Jack & Jill) is worried about having a child that has Tay-Sachs because the man had a brother with the deadly disease. Since they wanted to have children, they sought the advice of a genetic counselor. During the course of the interview the sounselor determines that Jack's parents were not affected with Tay-Sachs, yet his brother had it. What is immediately known about the genotypes of the man's parents? Is the genotype...

Tay-Sachs Disease is an autosomal recessive disease. That means that it is carried on one of the autosomal chromosomes and that only individuals with the two recessive disease alleles will have the disease phenotype. John and Sue are both carriers of the disease. Use the letters T and t to represent alleles. a.) What is John’s genotype? b.)Sue’s genotype? c.) What percentage of their children would you predict to have Tay-Sachs Disease? Show your work with a Punnett square.

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...
