Presentation Transcript

  1. What does a self-pollinating plant contain?

  2. anthers and a stigma

  3. What is the mathematical chance that an event will occur?

  4. probability

  5. What is the passing of traits from parents to offspring?

  6. heredity

  7. The inherited combinations of alleles is known as the offspring’s _____________.

  8. genotype

  9. _____________________used plants to study the way traits are passed from parents to offspring.

  10. Mendel

  11. If two first-generation self-pollinating plants are crossed, Pp and Pp, what is the probability that offspring plants will show the dominant trait? Create Punnett Square

  12. 3/4

  13. When pollen from one flower or plant can fertilize the eggs of the same flower or the eggs of another flower on the same plant, it is said to be ______________________.

  14. Self-pollinating

  15. The organism’s appearance is known as its ____________________ .

  16. phenotype

  17. What did Mendel remove from a plant so that it could NOT self-pollinate?

  18. anthers

  19. The trait that always appears in the first-generation offspring is the ___________.

  20. Dominate trait

  21. In _____________________ the anthers of one plant are removed so that the plant cannot self-pollinate.

  22. Cross-pollination

  23. The trait that seems to recede in the background in first-generation offspring is the ___________________.

  24. Recessive trait

  25. True or False? Alleles can be either dominant or recessive?

  26. True

  27. Create a Punnett Square for the following: • R = red flower • r = white flower • A Homozygous white flower with a heterozygous red flower. • What is the ratio of red to white flowers?

  28. Smooth pods = 56 • Bumpy pods = 82 • What is the ratio of bumpy to smooth pods?

  29. 82:56

  30. Each parent donates a set of instructions, known as _____________.

  31. genes

  32. A _______________________ plant will always produce offspring with the same trait as the parent.

  33. True-breeding
