1. Huntington’s disease is a dominant allele (not sex linked) that usually does not manifest itself until after age thirty- five. Individual who have the disease are almost always heterozygous. As a genetics counselor, you are visited by a 23-year-old woman. Her mother has Huntigton’s, but her father is normal. Use alphabets when required. a. What is the genotype of the mother?

b. What is the genotype of the father?

c. What is the probability that this woman will develop Huntington’s disease as she grows older ?

I DONT UNDERSTAND IT

The human genome project is devoted to mapping the general dna sequence of our species. this could lead to the development of new medicines, as well as the possibility of using gene therapy to treat certain diseases. however, there are some ethical issues surrounding the mapping of individual genomes. one concern is a) that your genes may change over time, making the project useless. b) that insurance companies could discriminate based on genetic make-up. c) that since this has never been done before, we should probably not do it now. d) that sequencing our individual genomes is so expensive, it is a counter-productive strategy.

Animals have a variety of adaptations,including trachea and gills, which allow this key process to occur. which provides the molecules necessary for cellular respiration and efficient atp synthesis?

Why do you suppose the structural polysaccharide cellulose does not contain branches?
