Phenotype - ANSWERSStructure and function of an individual

Crossing-over - ANSWERSThe exchange of genes between homologous chromosomes, resulting in a mixture of parental characteristics in offspring Mutation - ANSWERSRandom permanent changes in the sequence of nucleotides (A, T, C, G) Genetic Drift - ANSWERSThe change in the allele frequencies in a population that purely by chance events Population Bottleneck - ANSWERSOccurs when the size of a population is greatly reduced, some alleles may be lost or change in frequency Founder Effect - ANSWERSOccurs when a small number of indictable leave their home-large population and colonized a new area bringing a small amount of genetic variantion Nonrandom mating - ANSWERSWhen individuals prefer mates with particular or superior physical characteristics Positive Assortative Mating - ANSWERSIndividuals mate preferentially with others Inbreeding - ANSWERSPreferential mating among relatives Natural Selection - ANSWERSWhen two forces are at work. Genetic variation. When certain geno/phenotypes that are favored to survives and reproduce Fitness - ANSWERSA measure of the genetic information contributed to the next generation by an individual (number of surviving offspring produced by the individuals) Stabilizing Selection - ANSWERSExtreme phenotype are less fit Directional Selection - ANSWERSOne extreme phenotypes is the fittest Disruptive Selection - ANSWERSTwo or more extreme phenotypes are fitter than the intermediate phenotypes Natural Selection (Examples) - ANSWERSAnimals skin or coat color blending in with the background Fossils - ANSWERSRemains or impressions of an organism from a past geological time that has been preserved by natural process Speciation - ANSWERSThe "formation" of a new species over geological time Dispersal - ANSWERSMovement of individuals from their source location to another location where they might establish and reproduce

Cosmopolitan - ANSWERSSpecies with very large geographic ranges that can span several continents Semelparity - ANSWERSReproduce only once during their life Interparity - ANSWERSReproduce multiple times during their life; i.e. Most animals Modular Animals - ANSWERSReproduction is by asexual cloning, form colonies, or genetically identical organisms Unitary animals - ANSWERSDo not form colonies, must reproduce sexually, but some can reproduce by parthenogenesis Community - ANSWERSA dynamic and interactive group of populations from different species coexisting in a defined geographical area Ecosystem - ANSWERSIncludes all of the populations of organisms living in certain area plus their physical environment Food Web - ANSWERSA lot of animals have flexibility, so they can go after multiple preys Herbivore - ANSWERSConsumes plants and algae Predator - ANSWERSKills and consumes animals Detritivore - ANSWERSConsumes dead material Omnivore - ANSWERSConsumes plants and animals Filter Feeder - ANSWERSSuspension feeding animals fed by straining suspended matter and food particles from water Competition - ANSWERSInteraction between organisms, populations, or species, in which birth, growth, and death depend on gaining a shape of a limited environmental resource Active hunting strategies - ANSWERSPredators spend most of the time looking for prey Ambush hunting strategies - ANSWERSWaits for prey to walk by Mesopredators - ANSWERSRelatively small carnivores that consume herbivores Top Predators - ANSWERSPredators that typically consume both herbivores and mesopredators

Generalists - ANSWERSSelect and eat a wide variety of food items Specialist - ANSWERSFeeding upon a single species or a restricted range of closely related species Cryptic Coloration - ANSWERSMatch the background or resemble some inedible feature of the environment Aposematic coloration - ANSWERSToxic or distasteful animals advertise their strategy with bright colors and conspicuous behavior Mimicry - ANSWERSMatching animal animal to attract prey Parasitism - ANSWERSAcquire resources at the expense of a living host Modes of Transmission - ANSWERSIngestion, vectors, skin penetration, breathing in eggs, physical contact Mutualism - ANSWERSA positive interaction between two species in which each species receives benefits that the other species can provide Parasitoids - ANSWERSDifferent groups of insects
