Question

Mendel crossed tall and rounded seeds with short and wrinkled, in F${}_2$ generation he saw 1/16 were short and wrinkled seeds, What did he conclude from this?

• A. Short and wrinkled show linkage.
• B. Tall and wrinkled never combine.
• C. They show independent assortment.
• D. None of the above.

Answer 1

Answer: (C)

They show independent assortment.

When a cross between tall and rounded seeds plants was done with short and wrinkled seeds plant, tall and round seeded plants were obtained (in F${}_1$ generation). When F${}_1$ generation was selfed, a single dwarf plant with wrinkled seeds reappeared in F${}_2$ generation. This shows that the recessive gene was present and separated out independently during the production of gametes.

Thus, the correct answer is option C.
