Why Was the Theory of Blending Inheritance Eventually Disproven

question 5

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.
