Transcription de la présentation

  1. Gregor Mendel The Father of Genetics

  2. He was an Augustinian monk who later became the abbot of his monastery. 1. Who was Gregor Mendel? The Abbey of Saint Thomas and its Church in the year 1926. http://www.augnet.org/OrderStAugustineSECTION5/OrderHistory/OrderPlaces/Europe02/0331-Brno01.html

  3. When & where was he born? • He was born in 1822 in what is now the Czech Republic. http://www.oktours.cz/accommodation/hotels/czech/

  4. He was educated as a math & science teacher, and became interested in botany (plants). He did research on plants in the monastery. He is the “Father of Genetics.” 3. What did Mendel do for a living? 4. What is his title?

  5. The abbey garden where Gregor Mendel conducted his experiments. http://www.augnet.org/OrderStAugustineSECTION5/OrderHistory/OrderPlaces/Europe02/0331-Brno01.html

  6. He studied pea plants. He studied dwarf (short) and tall plants. 5. What species of plant did he mainly study? http://www.crop.cri.nz/home/products-services/crop-production/index.jsp 6. What size plants did he study? http://www.emc.maricopa.edu/faculty/farabee/BIOBK/BioBookgenintro.html

  7. 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)

  9. 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. 8. How long did he study these plants? 9. What sparked his interest in these plants?

  10. 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

  11. 10. What happened when he bred 2 pure dwarf plants (tt)?Do the punnett square

  12. Homozygous recessive parents

  13. 11. What happened when he bred 2 pure tall plants (TT)?Do the punnett square

  14. Homozygous dominant parents

  15. 12. What happened when he bred 1 pure dwarf with 1 pure tall plant?Do the punnett square

  16. Homozygous recessive and dominant parents

  17. 13. What happened when he bred the offspring of this match (Tt)?Do the punnett square

  18. Heterozygous parents

  19. 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. 16. What is a true-breeder? 17. What is a non-true-breeder?

  20. 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. 18. Why did Mendel stop his work? 19. When did Mendel die?

  21. 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. 20. When was Mendel’s work discovered?

  22. What controls a person’s features or characteristics? Genes How do organisms get these features/characteristics? They inherit them from each parent. How many do they inherit from each parent? ½ from each parent. Final Thoughts

  23. How do genes “travel” and settle down? They travel in pairs. 5. Why do some families have all brown hair? That is probably a dominant trait in that family. Final Thoughts
