Review Questions
Mendel performed hybridizations by transferring pollen from the _______ of the male plant to the female ova.
- anther
- pistil
- stigma
- seed
Hint:
A
Which is one of the seven characteristics that Mendel observed in pea plants?
- flower size
- seed texture
- leaf shape
- stem color
Hint:
B
Imagine you are performing a cross involving seed color in garden pea plants. What F1 offspring would you expect if you cross true-breeding parents with green seeds and yellow seeds? Yellow seed color is dominant over green.
- 100 percent yellow-green seeds
- 100 percent yellow seeds
- 50 percent yellow, 50 percent green seeds
- 25 percent green, 75 percent yellow seeds
Hint:
B
Consider a cross to investigate the pea pod texture trait, involving constricted or inflated pods. Mendel found that the traits behave according to a dominant/recessive pattern in which inflated pods were dominant. If you performed this cross and obtained 650 inflated-pod plants in the F2 generation, approximately how many constricted-pod plants would you expect to have?
- 600
- 165
- 217
- 468
Hint:
C
A scientist pollinates a true-breeding pea plant with violet, terminal flowers with pollen from a true-breeding pea plant with white, axial flowers. Which of the following observations would most accurately describe the F2 generation?
- 75% violet flowers; 75% terminal flowers
- 75% white flowers in a terminal position
- 75% violet flowers; 75% axial flowers
- 75% violet flowers in an axial position
