AP LAB 1: Hardy Weinberg Equilibrium
|
|
Conditions for a population or an allele to be in Hardy-Weinberg equilibrium are:
(1) a large population size,
(2) absence of migration,
(3) no net mutations,
(4) random mating,
(5) absence of selection
These conditions are RARELY met.

AP LAB 2: Natural Selection
Overview:
a. According to Darwin’s theory of natural selection, competition for limited resources results in differential survival. Individuals with more favorable phenotypes are more likely to survive and produce more offspring, thus passing traits to subsequent generations.
b. Evolutionary fitness is measured by reproductive success.
c. Genetic variation and mutation play roles in natural selection. A diverse gene pool is important for the survival of a species in a changing environment.
d. Environments can be more or less stable or fluctuating, and this affects evolutionary rate and direction; different genetic variations can be selected in each generation.
e. An adaptation is a genetic variation that is favored by selection and is manifested as a trait that provides an advantage to an organism in a particular environment.
f. In addition to natural selection, chance and random events can influence the evolutionary process, especially for small populations.
