Score 0/97 Timer 15:00
physical manifestation of expressed genes
mating behav., courtship rituals differ
pioneers change habitat to make favorable for spp.
short limbs, extra fingers
two or more genes determine a single phenotype
when spp evolve differences that reduce competition
all the genes contained in its diploid cell
non-toxic mimic toxic to confer protection
tendency for ecosystems to become more complex over time
place on chromosome where alleles are
anatomical incompatibility
makes histones unwind, making transcription easier
when organism focuses life on single reproductive event then die
phylogenetic tree w/fewest evolutionary events is most likely
mates chosen on basis of physical/behav. characteristics
long lived, reproduce later on in life
speciation independent of geography
movement of genes from 1 pop to another
theoretical exponential growth of an organim
pop. almost becomes extinct, revives, but has limited genetic variation
DES (diethylstibestrol), hexachlorobenzene, Ni+
a gene that limits the production of the phenotype of an allele
low rate of growth
changes that occur that inhibit growth of pioneer spp
Chixulub crater = evidence; ~1/2 all spp. lost
burst of new spp. from a single lineage
change in 1 to a few nucleotides
uncontrolled growth of a cell
two genes for the same trait
what you use to determine if a pop. is evolving or not
the evolutionary history of an organism
pioneer spp. tolerant of harsh abiotic conditions
high E; knocks e-s off atoms, creating free radicals
device used to determine genotype of offspring
2 or more pops. diverge b/c of geographical isolation
says father interested only in growth of offspring at expense of mom
resources than are in short supply
isolated population becomes diff. from original population
individuals that can't repair UV damage
when toxics evolve similar coloration
similar structures that evolved from different lineages
acquisition of same physical trait from different lineages
no functional protein produced
when evolution subdivides niche for spp
differing lifestyles or habits in pops.
increases frequency of extremes
250 mya; 90+% spp. on land and sea lost
chemicals that alter existing DNA nucleotides; OR nucleotide look-alikes
offspring differ from both parents
agent that increases mutation rate
when spp have overlapping niches
mates chosen on basis of physical/behav. characteristics
group of organisms that can interbreed & produce fertile offspring
pops. breed at diff. times of day, year, or diff. years
selects against extremes in phenotype
limit a community can handle to sustain pops.
says genetic makeup of small new group will slowly change in composition if small group doesn't contain same gene frequencies as ancestral group
missing section of DNA
what an organism requires of its environment
two genes for two traits
same species in the same geographical area
community + abiotic factors
gametes incompatible
some traits that don't enhance fitness selected because members of opp. sex find attractive
when allele expressed is determined only by which parent contributes
reversible changes in gene expression w/o changes to DNA
genes that seem to be linked to all types of cancer
similarities inherited from a common ancestor
fcnal unit of evolution
repeated section of DNA
identification & classification of organisms
more than 1 complete set of chromosomes
graded change in a trait along a geographical axis
probability of survival vs. age
no 2 spp can occupy same niche indefinitely
movement of gene on chromosome
classification that includes evolutionary affinities and history of spp.
gene that affects more than one phenotype
shifts freq. of trait a certain direction
cmpds that affect histones/methylation; increase cancers
evolution has periods of stasis and also sudden explosions of new spp.
causes adjacent pyrimidines to become linked chemically
expressed allele
consequences that result from reproducing
nonliving component of ecosystem
fewer offspring for more years
species that have a high rate of growth
reproduce as fast as possible
alternative state of a gene
difference in survival and reprod. b/c of diff. in genotypes
body size increases as you go north
theoretical community that reaches a steady state
extremities get shorter as you go north
binds to cytosines on DNA, winding DNA, making transcription more difficult
change of genetic info of a cell
tells when organism spp reproduces, how many babies, how old it gets
