  1. Potpourri of Human Genetics

  2. Genome • The entire hereditary information of an organism encoded in the DNA. • 3,200,000,000 base pairs in the Human Genome. • Fish have 130,000,000,000 base pairs • e. Coli have 4,600,000 base pairs • Honeybee has 236,000,000 base pairs

  3. Human Blood Types • Human Blood Alleles: A, B, O • Co-dominant Alleles: A and B • Recessive Alleles: O http://www.redcrossblood.org/learn-about-blood/blood-types

  4. Causes of Genetic Diseases • Mutations- random, spontaneous change in the DNA • Sex-Linked- disease passed to next generation through sex chromosomes • Deletion-Part of the chromosome is missing • Translocation- Part of a chromosome gets transferred from one part to another. http://www.youtube.com/watch?feature=player_detailpage&v=2CsgXHdWqVs Cri du Chat

  5. Sex Chromosomes • Female Chromosomes: XX • Male Chromosomes: XY • Gender is Determined by: Male

  6. Sex-Linked Traits • Carried on the: Sex Chromosomes • Examples: Red-green Color blindness, Hemophilia, Male Pattern Baldness, Duchenne Muscular Dystrophy

  7. Hemophilia • Punnett Squares
