Question

Even in Darwin's time, the blending hypothesis was incompatible with observed facts. If the blending hypothesis were true, then what should one expect to observe over the course of generations?A) Phenotypic polymorphisms should increase.

B) Genetic variation should increase.
C) Members of a breeding population should become more uniform in phenotype.
D) Neutral variation should decrease.
E) Genetic polymorphisms should increase.

Answer 1

C) Members of a breeding population should become more uniform in phenotype.

Step-by-step explanation:

The blending hypothesis was the accepted theory during the time of Charles Darwin and the Gregor Mendel.

The blending hypothesis suggested that the traits which arise in the offspring is the intermediate form of the mother and father that is if short male crossed with a tall female then will result in the intermediate height of the offspring.

This theory has many limitations as the evidence does not support the theory and also the next generation formed will be more uniform than the previous generation.

Thus, Option-C is correct.
