and Answers 100% Correct
Gregor Mendel✔✔An Austrian monk and math teacher who developed a strong interest in
statistics and heredity. He conducted experiments with pea plants where he would cross-pollinate
plants and study the inheritance patterns that would occur.
Pea Plant Experiments✔✔A series of experiments conducted by Gregor Mendel where Mendel
numbered each plant, and removed stamens from purple-flowered pea plants. Next, he
transferred pollen from the stamens of white-flowered pea plants to the carpels of purple flowers.
Once the carpel matured into a pod, the seeds were planted. Finally, the offspring were
examined.
Mendel's Principles of Dominance and Recessiveness✔✔1. Each trait of an organism seems to
be controlled by some form of physical factors that are passed from parent to offspring.
2. Whatever these factors are, they must occur and happen in pairs.
3. Each trait seems to have two possible forms of a factor.
4. One form of the factor seems to be stronger than the other.
5. When an individual inherits a pair of factors that include the two different types, the dominant
factor will mask the presence of the recessive factor. The individual will only show the effects of
the dominant factor.
Mendel's Principles of Segregation✔✔1. During the production of the gametes in the parent
organisms, the pair of factors that exist for each trait are somehow segregated from each other.
2. Each gamete receives only one factor for each trait.
3. The union of the two gametes restores the presence of pairs of factors for each trait in the
offspring.
