Important Points
- Gregor Mendel is known as the "father of genetics".
- Particulate Theory of Inheritance - traits are inherited as "particles", offspring receive a "particle" from each parent.
- Mendel's Experiments:
- Mendel chose pea plants as his experimental subjects, mainly because they were easy to cross and showed a variety of contrasting traits (purple vs white flowers, tall vs short stems, round vs wrinkled seeds).
- He crossed a true-breeding plant with a plant of the opposite trait (purple x white). He called this the Parental (P) generation.
- Mendel established three principles (or Laws) from his research:
- The Principle of Dominance and Recessiveness - one trait is masked or covered up by another trait.
- Principle of Segregation - the two factors (alleles) for a trait separate during gamete formation.
- Principle of Independent Assortment - factors of a trait separate independently of one another during gamete formation, another way to look at this is, whether a flower is purple has nothing to do with the length of the plant's stems - each trait is independently inherited.
