Gregor Mendel, a monk, formulated the following principles from
observations he made during the cross-breeding of pea plants.
- The Principle of Unit Characters
states that individuals pass information on as individual traits.
- The Principle of Dominance states
that some unit characters can mask the expression of others.
- The Principle of Segregation
states that each unit character separates into a different sex cell.
- The Principle of Independent
Assortment states that genes segregate according to chance.
