How were the pairs of true-breeding pea plant varieties similar?

Options

  1. AThey were similar except for one character with contrasting traits
  2. BThey were genetically identical
  3. CThey were similar in all traits
  4. DThey had no similarities

Correct answer

A. They were similar except for one character with contrasting traits

Step-by-step solution

Mendel conducted such artificial pollination/cross pollination experiments using several true-breeding pea lines. A true breeding line is one that, having undergone continuous self-pollination, shows the stable trait inheritance and expression for several generations. Mendel selected 14 true-breeding pea plant varieties, as pairs which were similar except for one character with contrasting traits. Some of the contrasting traits selected were smooth or wrinkled seeds, yellow or green seeds, inflated (full) or constr
