Mendel's study of 'either/or' traits in pea plants (like seed color and plant height) was crucial for what reason?
Mendel's study of 'either/or' traits in pea plants (like seed color and plant height) was crucial for what reason?
- It directly demonstrated the molecular structure of DNA.
- It enabled other scientists to replicate his experiments with different plant species.
- It simplified the data collection and made it easier to identify patterns in inheritance. (correct)
- It allowed him to create new varieties of pea plants with unique combinations of traits.

Study Notes
- Gregor Mendel, an Augustinian monk, is known as the founder of modern genetics.
- Mendel discovered the laws of heredity.
- Mendel realized family traits are inherited through units now known as genes.
- Johann Mendel was born to peasant farmers in what is now the Czech Republic.
- Mendel initially trained in math and philosophy before joining the priesthood for further education.
- He was renamed Gregor upon joining St. Thomas's Abbey in Brno.
- Mendel went to Vienna University, then taught at the abbey.
- Mendel focused on peas to help monks improve crop yields, inspired by plant breeding and heredity.
- His background in mathematics aided in designing experiments.
- Mendel examined "either/or" traits like seed color, flower color, and plant height to ease interpreting results.
Generations of Pea Plants
- Mendel crossed green and yellow seeded peas.
- The next generation of seeds were all yellow.
- Two offspring were crossed, revealing further genetic patterns.
Milestones in Mendel's Life
- 1851: He worked as a teacher and friar, and went to the University of Vienna to study.
- 1854: Mendel was authorized to study the St. Thomas's Abbey garden.
- 1856: Mendel started cultivating peas.
- 1866: Mendel published his experiments in Plant Hybridization, the significance was unappreciated at the time.
- 1868: Mendel became Abbot of St. Thomas's and stopped scientific research.
