6 Questions
What did Mendel investigate in the garden pea plant?
The characters manifested as two opposing traits
What did Mendel observe about the F1 progeny plants in his hybridisation experiment?
They were all tall
What did Mendel use in his experiments?
True-breeding pea lines
What is the first hybrid generation also called?
Filial progeny
What was significant about the sampling size in Mendel's experiments?
It was large, which gave greater credibility to the data he collected

It was never seen in the F1 generation
Study Notes
- Gregor Mendel conducted hybridisation experiments on garden peas from 1856-1863.
- Mendel proposed the laws of inheritance in living organisms.
- Statistical analysis and mathematical logic were applied to problems in biology for the first time during Mendel's investigations.
- Mendel's experiments had a large sampling size, which gave greater credibility to the data he collected.
- Mendel investigated characters in the garden pea plant that were manifested as two opposing traits.
- Mendel set up a basic framework of rules governing inheritance, which was expanded on by later scientists.
- Mendel used several true-breeding pea lines in his experiments.
- A true-breeding line is one that shows stable trait inheritance and expression for several generations.
- Mendel selected 14 true-breeding pea plant varieties as pairs which were similar except for one character with contrasting traits.
- Mendel's selected traits included smooth or wrinkled seeds, yellow or green seeds, inflated or constricted green or yellow pods, and tall or dwarf plants.
