Summary Introduction
Introduction: Tay–Sachs disease is caused due to mutations in the HEXA gene that encodes lysosomal enzyme. It follows autosomal recessive inheritance, that is, two copies of mutated gene are required for the occurrence of the disease.

Duchenne muscular dystrophy is sex linked and usually affects only males. Victims of the disease become progressively weaker, starting early in life.a. What is the probability that a woman whose brother has Duchenne’s disease will have an affected child?b. If your mother’s brother (your uncle) had Duchenne’s disease, what is the probability that you have received the allele?c. If your father’s brother had the disease, what is the probability that you have received the allele?
15. The following pedigree shows inheritance of Huntington's disease, a fatal genetic
disorder that causes neurodegeneration. Since signs and symptoms usually do not
appear until adulthood, many who are carriers may not realize their risk of passing on
the disease-causing allele. The following pedigree represents a family in which some
people are affected by Huntington's disease.
