- continuous variation
- founder effect
- stabilizing selection
- a selection pressuresd that favor average phenotypes. Stabilizing sleection reduces the amount of variation in the population but doesn't alter the mean value of the trait.
- b ex: height in humans, birthweight
- c occurs when a new colony is started by a few peope from the original population. Not much diversity, usually mutations.
- d genes that influence multiple traits
- e the shown trait
5 Multiple choice questions
- a FEATURE of an organism CREATED by the process of natural selection.
- the process of division of normal body cells through which new diploid cells are created
- a steady state in which two or more alleles coexist in a population.
- speciation that occurs when two or more populations of a single species are geographically isolated from each other and then diverge to form two or more new species
5 True/False questions
reproductive isolation → driving force behind sympatric speciation extreme values for a trait are favored over intermediate values. E.g.: large nose rather than medium sized nose
mutation → a FEATURE of an organism CREATED by the process of natural selection.
natural selection → the process that produces adaptation
character displacement → the process that produces adaptation
parapatric speciation → two-step process in speciation where selection causes the differentiation of geographically separate, isolated populations of a species and the populations become reproductively isolated as well
