Today's lesson
1. Introduce new topic: Heredity and evolution
2. Review DNA
3. Discuss Genotype and Phenotype

Slide 1 - Slide

Basics of heredity
  • Gene: part of your DNA with info on one trait 
  • You get one set of genes from your mom and one set of genes from your dad
  • For every trait you have two genes (pieces of info)
  • These pieces of info can be different variations of the gene
  • The combination of the two pieces decides what that trait will be for you

Slide 2 - Slide

Example:
  • Trait : Hair color - brown
  • Gene : part of the DNA carrying the info for this trait
  • Variations in this gene: blond, brown, red, black
  • Mother's hair : blond   x    Father's hair : brown
  • You : one gene (blond) x one gene (brown) = Brown hair

Slide 11 - Quiz

Genetic material
  • Genetic material is located in the nucleus of every cell.
  • Each nucleus has chromosomes  that contain DNA.
  • The genetic material is located in DNA molecules.
  • Nuclei of human cells have 46 chromosomes.

Slide 12 - Slide

A
46
B
23
C
22
D
45

Slide 13 - Quiz

Genotype

  • complete set of your inherited characteristics
  • information from DNA
  • you are born with it


Phenotype

  • your appearance 
  • seen from the 'outside' 
  • combination of genotype + environmental factors

Slide 14 - Slide
