What is a lineage
The five prezygotic isolating mechanisms
What is mechanical, temporal, behavioral, habitat & gametic
Charles Darwin's explanatory theory for evolutionary change
What is natural selection?
Number of era's in the history of life
What is (4) Four
In the Hardy-Weinberg Equilibrium equation p2 +2pq + q2... p2 represents
What is homozygous dominant (AA) genotype frequency
When lineages diverge may be revealed by
What is fossil records
A common misconception about the morphological species concept
Members of the same species do not always look alike
The origin of genetic variation
What is mutation?
These are needed to date an event
What is isotope concentration and isotope half-life
5 requirements for the Hardy-Weinberg Equilibrium to happen
What is no mutation, no gene flow, no selection of genotypes, infinite population size, and random mating
The order of biological classification
Kingdom --> Phylum --> Class --> Order --> Family --> Genus --> Species
Species must be _______ isolated to be considered separate lineages
What is reproductively isolated
Two types of genetic drift that often occur
What is Population Bottleneck and Founder Effect
Common causes for mass extinctions
Continental/ physical changes to Earth.
The way to restore a population to Hardy-Weinberg Equilibrium
What is (one generation of) random mating
Most widely used data for constructing a phylogenetic tree
What is DNA Sequencing
True or False, sympatric speciation is when populations are separated physically
What is False
True or False, far more individuals are born than survive to reproduce
What is true
As O2 increases, so do _______
What is larger, more complex organisms
Why all biological populations evolve
Equilibrium conditions are never met
Which species is the outgroup
What is panthera pardus
Genetically, the reason that hybrid organisms are often less fit for survival
*1 out of 3 is acceptable*
Hybrid zygotes will die during development or develop life-threatening abnormalities w/o ever reproducing
Hybridization causes too much change and results in a higher chance of death
Hybrid offspring are infertile.
Possible advantages of sexual reproduction evolving
What is facilitating repair of damaged DNA (chromosomal or sequences)
OR
What is elimination of deleterious mutations
Major atmospheric change in current/modern period of life
What is Climate Change/Global Warming; rapidly increasing CO2 concentrations
Read the following Hardy-Weinberg problem: the frequency of two alleles in a gene pool is 0.19 (A) and 0.81 (a).
Calculate % of heterozygous individuals
What is 31%
