Chapter 14 cornell notes

  1. 1. Chapter 14 Human Heredity CUE WORDS or QUESTIONS NOTES WRITTENWhat is a Chromosome? I. Human Chromosomes-Thread like structure within the II. Human Geneticnucleus that contains genetic III. Studying the Human Genomeinformation that is passed onfrom one generation to another. I. Human ChromosomesWhat Is a Karyotype? A. Karyotypes-an image of your entire 1. Sex Chromosomeschromosome. 2. Autosomal Chromosome Homologous pairsWhat is transmission? B. Transmission of Human TraitsWhat is autosomal? “What patterns of inheritance do human traits follow?”Why is blood O more rare? 1. Dominant and Recessive AllelesWhat is the difference of blood? 2. Codominant and Multiple Alleles-Antigen on the blood.Except O blood is rare. 3. Sex-linked Inheritance 4. X-Chromosome Inactivation C. Human Pedigree X II. Human Genetic Disorders A. From Molecule To Phenotype 1. Disorders Caused by Individual Genes A. Sickle Cell Disease *Problem with red blood cells* (1 Allele Change) B. Cystic Fibrosis *The body cant take up nutrients, it affects your digestion therefore most
  2. 2. people with this disease are skinny* (3 Bases Codon Delation) C. Hunting Ton’s Disease *Your brain starts breaking down* (CGA Repeat themselves 10-120x) *The more they repeat themselves the stronger the symptoms are* 2. Genetic Advantages A. Malaria and Sickle Cell Disease B. Typhoid and Cystic Fibroses B. Chromosomal Disorders 1. Nondisjunction “Not Coming Apart” III. Studying the Human Genome A. Manipulating DNA 1. Cutting DNA(Restriction Enzymes) 2. Separating DNA(Gel Electro Phoresis) 3. Reading DNA(PCR Poly Chain Reactions) *Making more DNA than what you got* X Figures 14.11 and 14.12 B. The Human Genome Project(1990)(Int. collaboration, com. In 2003) *Goal was to find out all the human genes* 1. Sequencing and identifying genes 2. Comparing sequences(international hap map project)(began 2002) 3. Sharing data(bioinformatics)(gen bank project) 4. What we have learned 5. New questions? 6. What’s next?SUMMARY X
