missing section of DNA
makes histones unwind, making transcription easier
chemicals that alter existing DNA nucleotides; OR nucleotide look-alikes
offspring differ from both parents
the evolutionary history of an organism
long lived, reproduce later on in life
DES (diethylstibestrol), hexachlorobenzene, Ni+
when toxics evolve similar coloration
burst of new spp. from a single lineage
non-toxic mimic toxic to confer protection
similar structures that evolved from different lineages
differing lifestyles or habits in pops.
pioneer spp. tolerant of harsh abiotic conditions
movement of genes from 1 pop to another
short limbs, extra fingers
when spp have overlapping niches
shifts freq. of trait a certain direction
change of genetic info of a cell
theoretical exponential growth of an organim
when organism focuses life on single reproductive event then die
what you use to determine if a pop. is evolving or not
evolution has periods of stasis and also sudden explosions of new spp.
same species in the same geographical area
says father interested only in growth of offspring at expense of mom
physical manifestation of expressed genes
phylogenetic tree w/fewest evolutionary events is most likely
identification & classification of organisms
says genetic makeup of small new group will slowly change in composition if small group doesn't contain same gene frequencies as ancestral group
nonliving component of ecosystem
reversible changes in gene expression w/o changes to DNA
a gene that limits the production of the phenotype of an allele
fcnal unit of evolution
agent that increases mutation rate
genes that seem to be linked to all types of cancer
more than 1 complete set of chromosomes
when evolution subdivides niche for spp
place on chromosome where alleles are
pioneers change habitat to make favorable for spp.
theoretical community that reaches a steady state
all the genes contained in its diploid cell
resources than are in short supply
no 2 spp can occupy same niche indefinitely
binds to cytosines on DNA, winding DNA, making transcription more difficult
body size increases as you go north
Chixulub crater = evidence; ~1/2 all spp. lost
tendency for ecosystems to become more complex over time
two or more genes determine a single phenotype
high E; knocks e-s off atoms, creating free radicals
uncontrolled growth of a cell
anatomical incompatibility
device used to determine genotype of offspring
community + abiotic factors
mates chosen on basis of physical/behav. characteristics
repeated section of DNA
mates chosen on basis of physical/behav. characteristics
some traits that don't enhance fitness selected because members of opp. sex find attractive
pop. almost becomes extinct, revives, but has limited genetic variation
no functional protein produced
individuals that can't repair UV damage
when allele expressed is determined only by which parent contributes
gene that affects more than one phenotype
pops. breed at diff. times of day, year, or diff. years
limit a community can handle to sustain pops.
250 mya; 90+% spp. on land and sea lost
selects against extremes in phenotype
similarities inherited from a common ancestor
two genes for two traits
reproduce as fast as possible
alternative state of a gene
classification that includes evolutionary affinities and history of spp.
2 or more pops. diverge b/c of geographical isolation
speciation independent of geography
gametes incompatible
change in 1 to a few nucleotides
extremities get shorter as you go north
what an organism requires of its environment
cmpds that affect histones/methylation; increase cancers
two genes for the same trait
consequences that result from reproducing
graded change in a trait along a geographical axis
increases frequency of extremes
mating behav., courtship rituals differ
probability of survival vs. age
expressed allele
low rate of growth
acquisition of same physical trait from different lineages
difference in survival and reprod. b/c of diff. in genotypes
isolated population becomes diff. from original population
fewer offspring for more years
when spp evolve differences that reduce competition
changes that occur that inhibit growth of pioneer spp
group of organisms that can interbreed & produce fertile offspring
causes adjacent pyrimidines to become linked chemically
movement of gene on chromosome
tells when organism spp reproduces, how many babies, how old it gets
species that have a high rate of growth
