Evolution
"Survival of the fittest" is used to describe this process.
What is natural selection?
TRUE or FALSE: Variation is important within a population because it increases a population's chance of survival.
What is true?
This type of selection favors one extreme phenotype over any another.
What is directional selection?
This is a group of organisms that are capable of mating and producing fertile offspring.
What is a species?
TRUE or FALSE: Populations that evolve experience a change in allele frequencies.
What is true?
This is an inherited characteristic that increases an organism's chance of survival.
What is an adaptation?
TRUE or FALSE: Evolution is a change in allele frequencies of an individual over time.
What is false?
The formula associated with allele frequencies.
What is p + q = 1?
New species arise when they become _______ .
What is reproductivly isolated?
This type of evidence is stronger for constructing a cladogram.
What is bimolecular or molecular?
Artificial Selection, Natural Selection, Founder Effect, and Bottleneck Effect are all examples of this process.
What is evolution?
Artificial selection is evolution of a population determined by this organism.
What are humans?
A population under Hardy-Weinberg Principle will NOT _________ .
What is evolve?
This type of isolation occurs before the formation of a zygote.
What is pre-zygotic isolation?
What are the three (3) things we can learn about an organism based on the fossil recored?
When they lived, where they lived, and what they might have looked like.
This is a well-supported, testable, and oftentimes observable explanation of phenomenon.
What is a scientific theory?
This type of genetic drift is a result of a small group of individuals colonizing (or occupying) a new habitat.
What is founder effect?
The formula associated with a population's genotypes.
What is p2+2pq+q2= 1?
This type of isolation occurs after the formation of a zygote.
What is post-zygotic isolation?
What trend is typically observed after a mass extinction event?
What is adaptive radiation?
When different species independently evolve similar traits or behaviors, even though they are not closely related.
What is convergent evolution.
This type of genetic drift is a result of a loss of genetic diversity in a population due to natural disasters.
What is bottleneck effect?
These are the five principals of Hardy-Weinberg equilibrium?
Random mating, large population, no mutations, no movement in/out of the population, no natural selection.
This type of isolation describes organisms who mating at different times of year.
What is temporal isolation.
DNA can not be synthesized without proteins (enzymes). Proteins can not be synthesized without DNA (instructions). Which came first?
What is RNA?
