Basic Terms
The union of 2 gametes
Fertilization
occurs when there is geographic isolation of a few members of the original population or species, and genetic drift occurs
Allopatric Speciation
fertilized egg cell that results from the union of 2 gametes
Zygote
the process by which genetic information is passed between organisms that are not related by parents or offspring
Horizontal Gene Transfer
What is my last name?
Carter
the study of evolutionary processes and patterns that occur above the species level
Macroevolution
Which two types of speciation are based on time?
Gradual Model and Punctuated Equilibrium Model
isolating mechanism that occurs when different species have incompatible anatomies
Mechanical Isolation
The giant ant eater and the echidna, who are in the same habitat, have both developed long snouts in order to feed on ants as their food source. What type of evolution is this?
Convergent Evolution
Who was the second president of the US?
John Adams
this is the offspring of members of two different species that interbreed and reproduce
Hybrid
A large-scale mutation occurs in an individual, and, over time, this mutation becomes extremely prevalent in a population, leading to the formation of a new species: what has occurred?
Sympatric Speciation
states that a biological species is a group of interbreeding natural populations that are reproductively isolated from other such groups (you need to say the scientist's name and the year)
Ernst Mayr's (1942) Biological Species Concept
The gene sequence for the p53 protein is found between 8 different organisms. This is an example of?
Genetic/Molecular Homology
How many colors are in the rainbow?
7 colors
drastic changes in chromosome number and/or chromosomal rearrangements
Polyploidy
True or False: speciation occurs through random processes
Which prezygotic isolating mechanisms occur before fertilization? (3)
Habitat Isolation, Temporal Isolation, and Behavioral Isolation

The frequency of the heterozygous genotype (EX. Aa)
What is the capital city of Germany?
Berlin
a hierarchical classification system for organisms that uses taxonomic categories
Linnaean Hierarchy
What kind of diagram shows the ancestry of species descended from common ancestors.
Phylogenetic Trees
What are the 3 postzygotic isolating mechanisms?
Hybrid Inviability, Hybrid Sterility, Hybrid Breakdown
In the Hardy-Weinburg Equilibrium Equation, if p = .55, what does q equal?
q = .45
