Transcript

  • 1. Mendelian Genetics Biology I Mr. Nettles
  • 2. Today’s Agenda – Wed. Nov. 16, 2011
    • Warm-up (Who is Gregor Mendel?)
    • Vocabulary Find
    • Any remaining time will be dedicated to A-Plus
  • 3. Today’s Objective
    • I will explore the life of Gregor Mendel.
    • I will define 16 key vocabulary term related to Mendelian Genetics.
  • 4. Warm-Up (Nov. 16)
    • Use an Internet Browser (Yahoo or Google) to search “Gregor Mendel.”
    • Take about 10 minutes to read about his life.
    • Take about 5 minutes to write three to five sentences about his life.
    • Share your findings with the class.
  • 5.
    • adenine and cytosine
    • cytosine and thymine
    • thymine and guanine
    • cytosine and guanine
    Which of the following shows the correct pairing of DNA bases? Cellular Energy Warm-Up (Nov. 14)
  • 6. Today’s Agenda – Mon. Nov. 21, 2011
    • Warm-up (EOC Practice Problems)
    • Genetics: Alleles, Monohybrid Crosses, Punnett Squares
    • Example Simple Genetics Problems
  • 7. Mendelian Genetics Biology I Mr. Nettles
  • 8. Today’s Objectives
    • I will explore the use of Punnett Squares to solve simple genetics problems.
    • I will understand the difference between homozygous and heterozygous.
    • I will understand the difference between genotype and phenotype.
    • I will understand the difference between dominant and recessive.
  • 9. Warm-Up (Nov. 21)
  • 10. Warm-Up (Nov. 21)
  • 11. Warm-Up (Nov. 21)
  • 12. Warm-Up (Nov. 21)
  • 13. Warm-Up (Nov. 21)
  • 14. Alleles
    • Alleles are different forms of genes.
      • Homozygous – both alleles are the same
      • Heterozygous – both alleles are different
  • 15. Dominant vs. Recessive
    • Dominant Allele – the expressed trait
      • it’s the trait that you see
      • usually represented by a capital letter
    • Recessive Allele – the masked trait
      • it’s the trait that’s covered up when a dominant allele is present
      • usually represented by a lowercase letter
  • 16. Dominant vs. Recessive
    • In Mendel’s pea plant experiment green was dominant over yellow.
      • G = green (dominant)
      • g = yellow (recessive)
    • The Alleles for Pea Plant Color
      • GG = homozygous green
      • Gg = heterozygous green
      • gg = homozygous yellow
  • 17. Monohybrid Cross
    • A monohybrid cross is the study of one trait only.
      • Mendel used monohybrid crosses to study pea plant color and form separately.
  • 18. Punnett Squares
    • Punnett Squares show possible combinations of alleles from genetic crosses.
  • 19. Punnett Squares
    • Phenotypes – physical characteristics
      • 3 purple flowers
      • 1 white flower
    • Genotypes – genetic makeup
      • 1 PP (homozygous purple)
      • 2 Pp (heterozygous purple)
      • 1 pp (homozygous white)
    Pp x Pp
  • 20. Quiz Tomorrow!!
    • Study Vocabulary Words from last week!!
    • Work example problems from handout!! (Hint, Hint)
    • Ask Mr. Nettles for help on the problems you don’t understand well!!
