He is the “Father of Genetics.”
4. What is his title?
The abbey garden where Gregor Mendel conducted his experiments. http://www.augnet.org/OrderStAugustineSECTION5/OrderHistory/OrderPlaces/Europe02/0331-Brno01.html
5. What species of plant did he mainly study? He studied pea plants.

7. What characteristics of the plants did he study?
Height (tall or short)Flower position (on side of stem or on top
of stem)Flower color (white or purple)Seed color (green or yellow)Seed shape (round or wrinkled)Seed pod color (yellow or green) Seed pod shape (inflated or constricted)
8. How long did he study these plants?
He studied them for about 8 years.
He noticed that he got offspring with different characteristics than their parents, and he wanted to know why.
9. What sparked his interest in these plants?
Genetic Vocabulary Genotype: the
genes, represented by 2 letters (tt, TT, Tt)
Phenotype: the trait or characteristic (tall or short)
Homozygous: same letters both upper case or both lower case (TT, tt)
Heterozygous: different letters (Tt) hybrid
16. What is a true-breeder? It is basically an organism that will
produce offspring which are identical to it. (Pure-bred)
It is an organism whose offspring are not necessarily identical to it.
17. What is a non-true-breeder?
18. Why did Mendel stop his work?He became too stout to successfully tend
his plants, and he had increased responsibilities due to his promotion to head abbot. Also, although he had published his findings in a scientific journal in 1865, his work was ignored.
He died in 1884, unsuccessful & alone. 19. When did Mendel die?
20. When was Mendel’s work discovered?His work was not discovered until 1900,
when 3 other scientists who had been looking at similar patterns stumbled upon Mendel’s research. They rightfully gave him credit as being the founding father for this new field in science.
Final Thoughts
1. What controls a person’s features or characteristics?
Genes
2. How do organisms get these features/characteristics?
They inherit them from each parent.
3. How many do they inherit from each parent?
½ from each parent.
