Exam 1 Flashcards
Natural Selection is Evolution? (T/F)
False
A 3 nucleotide sequence of DNA / RNA that corresponds to a specific amino acid is
A Codon
Who created the Law of Independent Assortment and Segregation?
Mendel
What was the name of Lamark’s Theory?
Theory of Acquired Characteristics
The change in the frequency of a population due to random sampling of organisms is called
Genetic Drift
Define Allopatric Speciation
A mode of speciation that occurs when biological populations become geographically isolated from each other to an extent that prevents or interferes with gene flow
Define Sympatric Speciation
The evolution of a new species from a surviving ancestral species while both continue to inhabit the same geographic region
Define Parapatric Speciation
When two subpopulations of a species evolve reproductive isolation from one another while continuing to exchange genes
Which cell division process creates daughter cells with only half of the genetic material from each parent?
Meiosis
In the HWE, the 2pq represents the frequency of the heterozygous genotype Aa (T/F)
True
The process of change over time is called?
Evolution
According to the biological species concept (BSC), a group of populations whose individuals have the potential to interbreed is defined as?
Species
Lord Bishop Samuel Wilberforce believed in evolution but not natural selection? (T/F)
False
Who co-founded Evolution by NS with Darwin?
Alfred Russel Wallace
Multiple possible alleles for a locus is a
Polymorphism
Genes that are closer together are more likely to recombine separately? (T/F)
False
Waston, Crick, & (blank) discovered the structure of DNA
Franklin
An STR is when a sequence of nucleotide bases is repeated over and over (T/F)
True
Natural Selection acts on the genotypes or the phenotypes?
Phenotypes
The (blank) allows for the calculation of divergence rates when one divergent rate is known
Molecular Clock
Random mating does not challenge allele frequencies (T/F)
True
Because of its assumptions, populations are never perfect in HWE (T/F)
True
The Scala Naturae is a scientifically backed organization of organisms (T/F)
False
(blank) counters genetic drift by adding variation back into a population
Mutation
(blank) alleles allow for variation beyond the initial range.
