An abnormality of the large intestine called intestinal polyposis (IP) is dependent on dominant gene A. A nervous disorder called Huntington’s chorea (HC) is determined by dominant gene H, a lethal gene the effects of which appear on a mean age of 40 years. A and H are on non-homologous chromosomes. A man carrying the gene A marries a woman carrying the gene H. If this couple had 7 children, a. what is the chance that at least 2 of their children will survive up to old age? b.  What are the genotypes of the man and his wife?

Health Epidemiology

Health is an essential factor for all human beings. For all humans, health is a critical factor. An individual's ability to meet life's challenges and retain his or her capacity for optimal functioning is reflected in his or her condition of health. This needs the physical, mental, and biological parts of one's constitution to maintain a degree of functioning that has a favorable influence and support for one another.
