What happened when Mendel self-pollinated the tall F1 plants?

Options

  1. AAll offspring were tall
  2. BAll offspring were dwarf
  3. CSome offspring were tall and some were dwarf
  4. DOffspring showed blended height

Correct answer

C. Some offspring were tall and some were dwarf

Step-by-step solution

Mendel then self-pollinated the tall F1 plants and to his surprise found that in the Filial2 generation some of the offspring were ‘dwarf’ ; the character that was not seen in the F1 generation was now expressed. The proportion of plants that were dwarf were 1/4th of the F2 plants while 3/4th of the F2 plants were tall. The tall and dwarf traits were identical to their parental type and did not show any blending, that is all the offspring were either tall or dwarf, none were of inbetween height
