One important conclusion of Mendel's genetic studies with pea plants is ____.
A) mutation is the only important factor in change
B) genes controlling traits do not blend during inheritance, but are transmitted as discrete entities
C) the traits that an organism inherits are the average of the two alleles
D) if particular traits do not appear in each generation, they are lost from the species
E) once a trait becomes recessive, it is lost to the population forever

Question

Quizplus · Accepted Answer

Mendel's experiments demonstrated that traits are controlled by discrete units of inheritance (now known as genes) and that these units are not blended together during reproduction. This idea forms the basis of modern genetics. The other answer choices are incorrect: A is too narrow, C is incorrect about the way traits are inherited, D is incorrect because recessive traits can still be present in a population, and E is incorrect because dominant traits can become recessive in some situations.
