Answer 1

The correct option is D Individuals inherit a smooth blend of traits from their parents.

During the 1800s, people widely believed in the Blending theory. It states that offspring of 2 parents would always have the average or mix of the traits of the parents

• For example, when two plants, one having white flower and the other having purple flower will be crossed, plants with pale purple flowers will be produced.

• This theory was widely believed before Mendel’s (Pre Mendelian era) work became public and got accepted by the scientific fraternity.

Offsprings produced by asexual reproduction have traits identical to their parents. This however was not a part of the blending theory.
