&Extinction
ALL of these animals are extinct. True or false?WoolyMammoth, Saber tooth Tiger, Stork
What is False
This is the name of the genetic drift effect where a large portion of the population is suddenly and randomly eliminated.
What is the Bottleneck effect
This type of diagram shows the evolutionary relationships amongst species based on shared characteristics
What is a Cladogram
A random change in allele frequency, especially in small populations
What is genetic drift
The sudden disappearance of a species from earth
What is extinction
Who is known as the father of evolution?
Who is Charles Darwin
This phenomenon occurs when a small group of individuals colonizes a new area leading to genetic variation that is different of the original population
What is the founder effect
This kingdom contains organisms like mushrooms and yeast which are heterotrophic and can decompose organic matter
What is Fungi
The founder effect and bottleneck effect are both examples of this
What is Genetic drift
On a cladogram 2 species are next to each other and share a recent common node, what does this suggest about their evolutionary relationship?
They share a recent common ancestor
A helpful change in an animals body
What is adaptation
Genetic drift has a stronger effect on populations of which size? Small, average, or large?
What is small populations
An organism that appears at the base of a cladogram and is used for comparison
What is an outgroup
This term describes all the genes in a population
What is a gene pool
Most ice in a forest have dark fur now when light fur used to be common, what likely happened?
What is natural selection
The process by which organisms change overtime through genetic variation
What is Evolution
The amish population in Pennsylvania is an example of this type of genetic drift where a small group founded a new population.
What is the founder effect
A shared trait found in a group of organisms and their ancestor
What is direct characteristic
A chain of allele frequency over time is called this
What is evolution
An island has only one small population of lizards, why is genetic variation low?
What is small gene pool and/or founder effect occurance
These four components are required for natural selection to occur
What is Variation, Inheritance, Overproduction, and Differential survival
How does genetic drift differ from natural selection?
genetic drift is random, natural selection is not
This kingdom includes multicellular autotrophic organisms with cell walls made of cellulose
What is plantae
Movement of alleles into or out of the population
What is gene flow
FOR 1000 POINTS
In a population under Hardy-Weinberg equilibrium, if the frequency of a recessive phenotype is 0.09 and the mutation rate from the dominant to recessive allele is 1×10⁻⁵ per generation, how many generations (approximately) would it take for the recessive allele to increase in frequency by 0.01 assuming no other evolutionary forces?
What is 1,111 generations
