Gregor Mendel: The Father of Genetics

Gregor Mendel The Father of Genetics

Before Mendel

• People knew that offspring inherited traits from
  parents.
• Most believed in the blended hypothesis that
  the offsprings traits were an equal combination
  of mother and fathers

Gregor Mendel was a monk, who lived Austria in
the mid 1800s.

Mendel Studied

• Seven traits in pea plants
• Seed form, seed color, flower color, pod form,
  pod color, flower position and stem length

5
What Mendel Found

• The principle of dominance Traits come in two
  forms. One form of a trait is dominant, the other
  form is recessive.

6
What Mendel Found

• The Law of Segregation Parents pass on one half
  of their (genes) to their young.

7
What Mendel Found

• The Law of Independent Assortment The (genes)
  that offspring inherit for one trait in no way
  influence the (genes) they inherit for other
  traits

Interestingly

• Mendel never knew about genes. He never once used
  the word. He knew that parents passed on
  controlling factors to their offspring, but he
  didnt know that these factors were pieces of DNA
  on chromosomes.
