What is when individuals select mates by their heritable traits.
200
What is a polygenic trait?
What is a trait controlled by two or more genes
200
What is stabilizing Selection
What is when individuals in the center curve have higher fitness then those on the ends of the curve
200
When would Geographical Isolation happen?
What is when two populations are separated by geographical barriers.
200
What are the two types of genes in a Gene Family
What is Hox and Globin
200
What are the 5 conditions evolution can occur under?
What is Non Random Mating, Mutations, Population Size, Immigration/emigration, and Natural Selection
300
What is Gene Pool and Allele Frequency?
What is the number of genes present in a population and the number of times an allele occur in a gene pool
300
What is the founder effect?
What is when allele frequencies change as a result of migration.
300
Why doesn't Geographical Isolation not always guarantee isolation?
What is linking/combining species together or separate some organisms, not all of them.
300
What does the Hox Gene determine?
What is development of arms, legs, body parts
300
What happens if two populations become reproductively isolated?
What is gene pools will diverge, making new species
400
What is Temporal Isolation
What is a form of Reproductive Isolation in which two or more species reproduce at different times
400
What was the Hardy-Weinburg principle?
What is allele frequencies stay constant unless one or more factors cause them to change
400
Waht are the three Isolating Mechanisms and give an example of each of them?
What is Behavioral, Geographic, and Temporal isolation and Using different behavioral methods for mating, mountains, and plants pollinate on different days
400
What is a mutation in a Hox gene called?
What is Ubx
400
How many genomes are in a molecular clock?
What is 1
500
What is a molecular clock and what is it used for?
What is the method used by researchers that uses mutation rates in DNA to estimate the length of time that two species have been evolving independently
500
How does natural selection affect Polygenic and Single trait genes?
What is can lead to changes in allele frequencies/phenotypes and affect the relative fitness of phenotypes
500
What is a current Hypothesis about the Galapagos Finches speciation?
What is Founding of a new population, Geographic isolation, changes in the population's gene, behavioral isolation, and ecological competition

What is the process when homologous chromosomes exchange DNA during meiosis.
