a. heterozygotes can be produced in two ways.

b. the population is doubling in number.

c. heterozygotes have two different alleles.

d. A and C only

Which of the following best describes the principle of evolution by natural selection?

A. Individuals within a population are genetically identical and natural selection occurs randomly

B. Individuals within a population exhibit genetic variation and those that are best adapted to their environment survive

C. Individuals within a population exhibit genetic variation and those that are least adapted to their environment survive

D. Individuals within a population undergo genetic mutation and natural selection occurs randomly

E. Individuals within a population exhibit genetic variation and natural selection occurs randomly

Adaptations are the characteristics of individual organisms--a reflection of the interaction of the genes and the environment. They are the product of natural selection. Although the process of natural selection is driven by the success or failure of individuals, the population--the collective of individuals and their alleles--changes through time, as individuals either succeed or fail to pass their genes to successive populations. Is there a good example to explain this concept? I need help understanding.
