1. …… is the passing of physical characteristics from parents to offspring. 2. One physical characteristic pass from the mother cat to the kitten was…

3. …… are physical characteristics that can be passed from parents to offspring. 4. One trait that was NOT passed from the mother cat to the kitten was.. 5. What do you think the father of the kitten looked like?...

6. ……is the study of heredity.

7. Mendel is considered the father of genetics. 8. Heredity is the passing of traits from parents to offspring and studying this passing of traits is called…… 9. The …… produce the male sex cells in flowering plants.

10. …… occurs when male and female sex cells join and a new organism begins to form. 11. An example of contrasting plant traits is… 12. A …… organism is the offspring of many generations that have the same trait. 13. Mendel prevented self-pollination by removing ….

14. In the __Parent Generation__, purebred …… plants were crossed with purebred …… plants. 15. In the __1st Generation__ – All of the F1 offspring were ……. None of the F1 plants were …… even though one parent was short. 16. In the __2nd Generation__ – The F2 offspring occurred in the ratio of …... tall plants to …… short plant. 17. Both parents of the F2 offspring were ……, but 1 in 4 F2 Offspring were short.

18. The short trait of one parent of the parent generation did not occur in the 1st generation, but reappeared in the 2nd generation. 19. In all of Mendel’s crosses, only one form of the trait appeared in the ….. generation. But, the “lost” form of the trait always reappeared in about one fourth of the plants in the …… generation.

Extra Credit 1: __Results of a Cross__ (Reproduce figure 2 on page 156 in its entirety.) When Mendel crossed purebred tall-stemmed plants with purebred short-stemmed plants, the first generation offspring all had tall stems. Then he allowed the first-generation plants to self-pollinate. About 75 percent of the offspring had tall stems, and about 25 percent had short stems.
