microevolution Flashcards
1
Q
Changes in population over time
A
Microevolution
2
Q
— exists in populations – different alleles
A
Genetic variation
3
Q
– Small changes in allele frequencies or different
combinations of genes in offspring over time in the same species
A
- MICROEVOLUTION
4
Q
When dramatic changes in allele frequencies
that a new species comes about.
A
MACROEVOLUTION
5
Q
2 Kinds of EVOLUTION
A
Microevolution and Macroevolution
6
Q
- Will affect which alleles make an organism fit or not in a population
A
Selection Pressures
7
Q
N is always on-going (as long
as the environment is changing then the allele
frequencies are always going to change)
A
*MICROEVOLUTION
8
Q
A principle that helps to predict allele frequencies in
a population.
A
Hardy-Weinberg Equilibrium
9
Q
It assumes no selection, no mutation, no geneflow,
random mating, and large populations for stable
allele frequencies.
A
Hardy-Weinberg Equilibrium
