|
q |
Stands for the frequency of recessive genes in a generation |
The q is how much the lesser is around Ex, non dominant gene |
|
|
Microevolution |
A change which occurs in a species that can occur within hundreds of generations |
The slight color change is due to micro evolution Ex, slight change |
|
|
Natural selection |
Most important factor that changes gene pools in large populations by increasing reproductive success leading to higher allele frequency |
The major change was natural selection Ex, moth black to white |
|
|
Gene flow |
The effects of migration between gene pools, makes geographically different gene pools similar |
The black panthers change to a new population is gene flow Ex, migrate |
|
|
Genetic drift |
Random change in allele frequencies mostly affecting small populations |
There was a genetic drift that made white moths slightly more than black Ex, flipping coin |
|
|
Founder effect |
Is a genetic drift that influences new populations |
There was a genetic drift when a couple left to start their own family on an island Ex, Darwin's finches |
|
|
Inbreeding |
A gradual increase in homozygosity due to populations limited to few organisms so mating occurs between close relatives |
The hics are known for inbreeding Ex, hics |
|
|
Population bottleneck |
The number of organisms is drastically changed for a few generations and this occurs in large populations |
There was a population bottleneck with the buffalo Ex, buffalo |
|
|
Inbreeding depression |
Fertility and survival is reduced compared with populations that are not inbred |
The hics can't have kids very well Ex, no kids |
|
|
Quantitive traits |
Multifactorial traits, affected by multiple genes and are on a continuous scale |
My weight is by quantitive traits Ex, weight |
|
|
Quantitive trait loci (QTLs) |
The genes that affect quantitive traits |
My weight isn't because of food it's because of QTLs Ex, cause of weight, etc |
|
|
Artificial selection |
This is an experimental breeding where the breeding is selective to develop a certain result |
The team was by artificial selection Ex, team |
