PPT-Human Genetic Disorders Chapter 11

CP Biology Genetic Disorders Major types of genetic disorders Autosomal Single genes Multiple genes Sexlinked Chromosome abnormalities Autosomal Disorders Autosomal genetic disorders are caused by alleles on autosomes chromosomes other than the sex chromosomes. Also its possible for otherwise healthy people to develop severe illness so any one concerned about their illness should consult their doctor There are emergency warning signs that should signal anyone to seek medical care urgently Emergency Warning Introduction. There are thousands of . genetic disorders. that affect humans, some of which can have profound effects on a person's quality of life. Genetic disorders are . passed from parents to offspring in the genetic . Isabel C. Ibarra Soto. Episcopal Cathedral School. This . project investigates all four types of genetic disorders in order to find out which is the most common among the Puerto Rican community. With this information, this project addressed how the Human Genome Project has helped the scientific community to find cures for this type of disorders. Throughout this extensive Internet research, it was found that the most common type of genetic diseases in Puerto Rican society are the . You can compare dogs of every breed imaginable! . There is an enormous range of characteristics that are the result of . genetic variation. . . The differences among breeds of dogs are so great that someone might think that many of these breeds are different species. . What has gone wrong?. 2. Certain human genetic disorders can be attributed to the inheritance of single gene traits or specific chromosomal changes, such as nondisjunction.. illustrative examples:. . Genetic disorders can be due to any of the following factors:. A. Monogenetic Disorders: Caused by a mutation in a single gene. Autosomal. recessive alleles:. a. You may be a carrier and not know it, since the dominant allele masks the recessive.. Project goals:. identify. all the approximately 20,000-25,000 genes in human DNA. determine. sequences of the 3 billion chemical base pairs that make up human DNA. Karyotype. Genetic Disorders. Major types of genetic disorders:. Video-Down Syndrome. http://www.sosq.vcu.edu/videos.aspx. The image you see is called a karyotype and there is a chromosome missing. How do you think this happens? . Work with a partner and answer the following question:. What is the difference between . the mice in these two groups?. What is genetic engineering?. Genetic engineering is the . direct modification of an organism’s genome. , which is the list of specific traits (genes) stored in the DNA. . Lectures. . – . 17x2 (Med); . 17x1. (. Stom. ). ;.
