  1. Introduction to genetics

  2. What is the genetic material

  3. S and R bacterial cellsStreprococcus pneumonia

  4. Hershy –Chase “blender” experiment using T2 bacteriophage

  5. Bacteriophage

  6. How genes are transmitted from parents to offspring?

  7. Classical or mendelian genetics • Gregor Mendel experiment on Garden peas 1856-1863

  8. Classical genetics depends on: • Phenotype: color , size , texture…etc. • Genotype: The genetic make up of the organism.

  9. Inheritance of seed textureMorphological phenotype W is dominant over the w

  10. Inheritance of seed textureMolecular phenotype

  11. Mendel first experimentInheritance of Genetic trait(s)

  12. Mendel first experimentreciprocal cross

  13. Results of Mendel first experiment

  14. Explanation of 3 dominant :1 recessive inheritance • Monohybrid cross • Independent assortment • Segregation

  15. The principal of the 3:1 inheritance Phenotype: Genotype:
