Why Was the Theory of Blending Inheritance Eventually Disproven

Multiple Choice

Why was the theory of blending inheritance eventually disproven?

A) Although the theory of blending inheritance accounted for a great deal of variation in a population, the theory of natural selection yielded explanations for every phenotype observed in a population.
B) The theory of blending inheritance suggested that inheritance is a diversifying force, but it is actually a homogenizing force.
C) It suggested that traits such as blue eyes were recessive, but such traits are in fact actually the result of rare dominant mutations arising in populations.
D) It was based on the fact that the phenotypes of progeny of a given cross typically resemble either parentand never present "intermediate" phenotypes (i.e., such as grey fur) .
E) It was eventually disproven by demonstrating segregation of alleles for the inheritance of many traits in diverse types of organisms.
