Genetics of populations
short period of time
What is Micro evolution?
New species evolving
What is Speciation?
Keep genes in a narrow window
What is Stabilizing Selection?
vary the alleles in a population
What is mutation?
Species change over time
What is Darwins theory?
Over geologic time
What is Macro evolution?
Geologic and climate conditions are stable
What is Gradualism?
Two extreme phenotypes are selected
What is Directional selection?
individuals move in and out
What is Gene flow?
Humans can breed plants and animals to have useful traits
What is Artificial selection?
Number of a specific species in a given area
What is Population?
New species without geographic separation
What is Sympatric Speciation?
Phenotypes in the middle of the range are selected
What is disruptive selection?
sudden decrease in a population
What is bottleneck effect?
the ability to survive
What is fitness?
All genes of all the members of a population
What is a gene pool?
Species in symbiotic relationships tend to evolve together
What is Co evolution?
difference fitness in a group
What is Natural Selection?
new population starts from a small group
What is founder effect?
English geologist who thought earth is much older than we think
random changes happen in a small population
What is genetic drifts?
Conditions are changing and evolution is happening more quickly
What is punctuated Equilibrium?
show how many alleles are found in a population
What is allele frequency?
The process in which organisms change over time
What is evolution?
French Naturalist who believed in inheritance of characteristics
Who is Jean Baptiste Lamarck?
