Term
Von Linne (Linnaeus)
Definition
classified organisms
gave them latin names
Principle of Fixity of Species
Term
Principle of Fixity of Species
Definition
all species created by God
no change
evident variation is inconsequential
Term
Lamarck
Definition
Theory of Inheritance of Acquired Characteristics (Theory of Use and Disuse)
Term
Theory of Inheritance of Acquired Characteristics (Theory of Use and Disuse)
Definition
all organisms have needs
organs change to meet needs
more use= more complex
less use= loss of organ
changes are inheritable
Term
Cuvier
Definition
Theory of Catastrophism
Term
Theory of Catastrophism
Definition
catastrophes caused organism to become extinct
new organisms migrated into to empty area
new organisms are similar to extinct
results in appeared adaptation
species do not change
Term
Lyell
Definition
Theory of Uniformitarianism
Term
Theory of Uniformitarianism
Definition
only forces present today were present in the past and only they could have caused past events.
Earth older than thought
Term
Maithus
Definition
Essay on Principle of Population
Term
Essay on Principle of Population
Definition
limited resources control population growth.
Term
year On the Origin of Species was published
Definition
1859
Term
Wallace
Definition
independently came up with same theory as Darwin
Term
year Mendel's experiment published
Definition
1866
Term
Principle of Segregation
Definition
genes come in pairs
one gene per sex cell
Term
Gene
Definition
segment of DNA that codes for a protein
Term
Allele
Definition
alternative forms of same gene
Term
genotype
Definition
set of genes possessed by individual
Term
phenotype
Definition
physical expression of genotype
Term
homozygous
Definition
2 copies of same allele
Term
heterozygous
Definition
1 one of each allele
Term
dominant allele
Definition
expressed phenotypically in homozygote and heterozygote
Term
recessive allele
Definition
expressed phenoypically only in homozygote
Term
Principle of Independent Assortment
Definition
segregation of one gene does not influence the segregation of another
more genotypes than phenotypes
Term
purpose of Mitosis
Definition
growth of organism and maintenance of organs.
daughter cells identical to parent (diploid #)
Term
chromosome
Definition
sequence of genes
Term
chromatids
Definition
identical chromosomes
Term
centromere
Definition
holds two chromatids together
Term
DNA base pairs
Definition
A-T
C-G
Term
nucleotides made up of
Definition
proteins
Term
proteins made up of
Definition
amino acids
Term
codon
Definition
set of 3 amino acids that codes for a protein
Term
Transcription
Definition
mRNA formed
Term
base pairs of RNA
Definition
A-U
C-G
Term
Translation
Definition
tRNA carries an amino acid that bonds to mRNA
Term
evolution
Definition
change in allele frequencies over time
Term
mutation
Definition
error in DNA replication resulting in new allele
Term
gene pool
Definition
all genes and alleles in a population
Term
population
Definition
community in which mating occurs
Term
allele frequency
Definition
ratio of one allele relative to all others
Term
Hardy-Weinberg conditions
Definition
random mating
infinite population growth possible
no natural selection
no migration
no mutations
Term
4 forces of evolution
Definition
mutation
gene flow
genetic drift
natural selection
Term
gene flow
Definition
exchange of alleles between populations
Term
genetic drift
Definition
change in allele frequency due to random events (ex. natural disaster)
Term
natural selection
Definition
survival of the fittest
advantageous traits inherited
Term
gradualism
Definition
evolution is gradual, continuous process due to natural selection
Term
punctuated equilibrium
Definition
evolution is not continuous but has periods of rapid speciations and periods of no change caused by mutation and genetic drift
Term
polymorphism
Definition
2 or more alleles for same gene. at least 2 have frequencies equal or greater than one percent
Term
balanced polymorphism
Definition
polymorphism due to heterozygotes being more advantageous
