Chapter 15
Descent with modification.
This drug was developed in 1943.
What is penicillin?
The change in gene frequencies between populations of a species over time.
What is microevolution?
Studies the diversity of populations at the level of the gene.
What are population genetics?
What is systematic biology?
A diagram that reflects evolutionary relationships.
What is an evolutionary tree?
Past evidence of an organism that has been preserved in earth's crust.
What is a fossil?
A group of organisms of the same species occupying a certain area and sharing a common gene pool.
What is a population?
p^2+2pq+q^2=1
What is the Hardy-Weinburg Equilibrium equation?
An evolutionary family tree.
What is phylogeny?
When individuals inherit better traits to survive.
What is natural selection?
Similarity in characteristics due to a shared ancestry.
What is homology?
Genetic drift, natural selection, and gene flow.
What mechanisms can cause the evolution of populations?
What is the bottleneck effect?
Uses shared, derived traits to develop a hypothesis of evolutionary history.
When bacteria and viruses reproduce very quickly and create resistant strains.
What is a super bug?
The alleles of all genes in all individuals in a population.
What is a gene pool?
The outcome of natural selection where extreme phenotypes are eliminated, and the average is conserved.
What is stabilizing selection?
Species with similar DNA base-pair sequences are more closely related.
What are molecular traits?
The intentional breeding of certain combinations of traits to produce a desirable outcome.
What is artificial selection?
All six plants that wild mustard was bred to be.
What is cabbage, kale, broccoli, cauliflower, brussel sprouts, and kohlrabi.
No mutations, migration, or selection.
What are the restrictions of the Hardy-Weinburg Equilibrium?
Protected from sickle cell and malaria and do not die from sickle cell.
What are heterozygotes?
One are similar phenotypes and genetics due to shared ancestry, the other are similarities that develop due to convergent evolution.
What is the difference between homology and analogy?
