Genetics:mendel powerpoint Presentation Transcript

  • 1. Mendel’s Laws of Heredity
    • Ch 10.1
  • 2. What is heredity?
    • The passing on of characteristices from parents to offspring.
    • Genetics is the branch of biology that studies heredity
    • the characteristics that are inherited are traits.
    • Mendel was the first person to success in predicting how traits would be transferred from one generation to the next.
  • 3. Medels Subject
    • He chose pea plants, which reproduce sexually, which means they have two distince sex cells, male and female.
    • sex cells are called gametes.
    • the transfer of male pollen grains to the pistil of a flower is called pollination
    • the uniting of male and female gametes is called fertilization
  • 4. Crosses
    • A hybrid is the offspring of parents that have different forms of a trait, such as tall and short.
    • Mendel first did monohybrid crosses, which means he was looking at only one trait.
  • 5. Mendel’s crosses
  • 6. The rule of dominance
  • 7. the law of segregation
  • 8. phenotype
    • the way an organism looks and behaves is called it’s phenotype.
      • example: what color are your eyes, or your hair?
      • what you see is the phenotype.
  • 9. Genotype
    • the gene combination an organisms contains is known as genotype.
  • 10. homozygous vs heterozygous
    • an organism that is homozygous for a trait has two alleles for the trait that are the same.
    • an organism that is heterozygous for a trait has two different alleles (dominant and recessive).
  • 11. punnett square
    • punnett sqaures are used to predict what possible offspring may be.
  • 12. dihybrid cross
  • 13. sources
