recognition as founder of the science of genetics (1822-1884)

2. For natural selection to work, offspring/progeny must inherit some kind of
genetic material from their parents.

3. Mendel's Experimental Model: purposefully cross-pollinated pea plants based o
features to make important discoveries on how traits are inherited between generations
4. 1. Each pea plant has a female part (ovules) and a male part (anthers), so plant

, reproduction can be easily manipulated by removing sex organs.
2. Pea plants have very observable traits (like white vs purple flowers). These
kinds of traits are called discrete traits
3. Pea plants produce many offspring very quickly.
- Many generations in a short time.: Advantages of Mendel's experimental model
5. Gene: An inherited factor (encoded in the DNA) that helps determine a characteristic
6. Allele: One of two or more alternative forms of a gene
7. Locus: Specific place/location on a chromosome occupied by an allele
