After the Rediscovery in 1900 of Gregor Mendel's Now-Famous Experiments

question 40

Multiple Choice

After the rediscovery in 1900 of Gregor Mendel's now-famous experiments from the 1850s and 1860s, evolutionary biologists viewed variation in two ways. What were these views and how were the differences eventually resolved?

• A) Mendelians viewed inheritance as continuous while biometricians viewed inheritance as discrete. Scientists eventually learned inheritance operates in both ways, leading to the modern, evolutionary synthesis.
• B) Mendelians viewed inheritance as discrete while biometricians viewed inheritance as continuous. Scientists eventually verified that inheritance acts in a discrete manner only, leading to the rejection of the blending theory.
• C) Mendelians viewed inheritance as discrete while biometricians viewed inheritance as continuous. Scientists eventually learned inheritance operates in both ways, leading to the modern, evolutionary synthesis.
• D) Mendelians viewed inheritance as continuous while biometricians viewed inheritance as discrete. Scientists eventually learned that inheritance is only continuous, verifying Darwin's theory of natural selection.
