Chi-Squared
What you need for performing a chi square test properly.
What is a large enough sample size?
The amount of mutation needed for a population to be in hardy-weinberg equilibrium.
What is none?
The diagram that displays multiple evolutionary relationships.
What is a cladogram?
The name for the process of humans selecting traits that they like or that are favorable.
What is artificial selection?
The term for when a species completely disappears from Earth.
What is extinction?
The type of data that is needed for a chi-squared test
What is categorized data?
The genotype that is represented by p^2.
What is homozygous dominant?
The shape that represents a female in a pedigree.
What is a circle?
The kind of selection that favors an "extreme" phenotype.
What is directional selection?
When many species die off in a short period of time
What is mass extinction?
A certain situation when a chi-squared test is not appropriate.
What is when the sample size is too small?
The genotype that is represented by q^2.
What is homozygous recessive?
The trait that most commonly separates amphibians from fish in many evolutionary trees.
What are legs?
The type of evolution when different, unrelated species develop similar traits/
What is convergent evolution?
When species are separated by a geographic barrier, creating a new species.
What is allopatric speciation?
What the tester can conclude when the chi-squared value is less than the critical value.
What is fail to reject the null hypothesis?
The value of p if q= 0.3
What is 0.7?
The point where a line "branches off" in a cladogram
What are nodes?
The certain evolutionary mechanism that heavily influences small populations, as well as being random.
What is genetic drift?
When a completely new species forms from another with no geographic barriers present
What is sympatric speciation?
The formula used for calculating chi-squared values.
What is ∑(O−E)²/E?
The NATURALLY occurring phenomenon that causes evolution which would also disrupt hardy-weinberg equilibrium.
What is natural selection?
The easiest way to determine how related species are in a cladogram.
What is referring to the most recent common ancestor?
The idea that organisms that are more suited to their environments will reproduce and survive more often.
What is natural selection?
When a population of a species sharply declines as a result of an environmental event.
What is the bottleneck effect?
