2
|
natural selection in which individuals at the upper and lower ends of the curve have higher fitness than individuals near the middle of the curve
|
|
4
|
form of reproductive isolation in which two populations are separated by geographic barriers such as rivers, mountains, or bodies of water, leading to the formation of two deprecate subspecies
|
|
5
|
random change in allele frequency caused by a series of chance occurrences that cause an allele to become more or less common in population
|
|
6
|
a change in allele frequency following a dramatic reduction in the size of a population
|
|
7
|
the number of times an allele occurs in a gene pool, compared to the total number of alleles in that pool for the same gene
|
|
9
|
all the genes that are present in a population (includes all different alleles for each gene)
|
|
10
|
form of natural selection in which individuals near the center of a distribution curve have higher fitness than individuals at either end of the curve
|
|
11
|
when individuals select mates based on heritable traits
|
|
12
|
movement of individuals into an area occupied by an existing population
|
|
13
|
change in allele frequencies as a result of the migration of a small subgroup of a population
