What was the main conclusion Mendel drew from the reappearance of white flowers in the F2 generation?

  • A: The blending hypothesis was correct.
  • B: The heritable factor for white flowers was lost in the F1 generation.
  • C: The heritable factor for white flowers was not lost or blended, but was masked by the dominant purple flower factor in the F1 generation.
  • D: Self-pollination is the only way to produce genetic variation.

Explanation

The 'Conclusion' in Figure 14.3 states: 'The 'heritable factor' for the recessive trait white flowers had not been destroyed, deleted, or 'blended' in the F1 generation but was merely masked by the presence of the factor for purple flowers, which is the dominant trait.'
