Fitness and selection
This difference in traits among organisms in a population help drive the process of natural selection.
What is variation?
This occurs because traits are often heritable and organisms compete to survive
What is natural selection?
When alleles are transferred between populations due to immigration
What is gene flow?
The first details relatedness, but the second also incorporates time
What are cladograms and phylogenetic trees?
This is two factors are required to create two separate species.
What is time and reproductive isolation?
Being able to survive and reproduce describes an organisms this.
What is fitness?
If the values of p and q change over a period of time in a population, then it said the population is doing this.
What is evolving?
When a cataclysm occurs the remaining allele frequencies are different than they were before the event
What is bottleneck effect?
This represents speciation events and common ancestors
What is a node?
This type of speciation occurs due to geographic isolation.
What is allopatric speciation?
An environmental factor that impacts whether an organism can survive and reproduce. ______________ pressure
What is selective pressure?
This is the variable that you must solve for first in any Hardy Weinberg equation.
What is q2?
When environments are similar they lead to the development of similar traits in two different lineages and the traits are called this
What is convergent evolution and analogous traits?
This lineage is the least closely related member of the clade
What is the outgroup/basal taxa?
Name one type of isolation or barrier that would cause sympatric speciation to occur.
What is behavioral, mechanical, temporal, or prezygotic?
This describes how sexually reproducing organisms will choose the best mate to reproduce with.
What is non-random mating?
If 30 out of 50 individuals have the dominant trait, how many are homozygous dominant assuming HW equilibrium?
7
These structures exist between organisms who share those types of ancestors
What are homologous traits and common ancestors?
These four things can be used to create cladograms
What are DNA, morphology, biogeography, and fossils?
True or False: Two species have many differences in their amino acid sequences for the same protein, meaning that speciation occurred very recently between these two groups.
What is false ?
What is genetic drift (small population), non-random mating, mutations, migration (gene flow), and natural selection?
Name the five assumptions for a population to remain in Hardy Weinberg equilibrium.
What is large population, random mating, no mutations, no migration (gene flow), and no natural selection?
This is the most specific evidence for evolution used to compare relatedness between species.
What is molecular (DNA/Amino Acids)?
This signifies a species is extinct on a phylogenetic tree.
What is an experiment that could demonstrate how life originated?
