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

Answer:

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

Explanation:

The blending hypothesis was the hypothesis which suggested that the produced offspring possess the intermediate characteristics of both the parents. This means that if the tall male and short female are crossed then the offsprings will have intermediate height.

This theory was well accepted at the time of Gregor Mendel and the Charles Darwin. This theory has limitation as the breeding population offsprings will have the uniform characteristics and the unformatism will be established.

Thus, Option-C is correct.
