- parapatric speciation
- what's a nucleotide composed of?
- a a phosphate-sugar base
- b evolution of populations within a species
- c carries genes and appears during cell division
- d many genes?
- e 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
5 Multiple choice questions
- the transfer of alleles of genes from one population to another
- occurs when a new colony is started by a few peope from the original population. Not much diversity, usually mutations.
- refers to cells that have pairs of homologous chromosomes, where one chromosome of each pair is inherited from each parent. All primates are diploid
- driving force behind sympatric speciation extreme values for a trait are favored over intermediate values. E.g.: large nose rather than medium sized nose
- structural similarities derived from two species with independent ancestors. Eg. a bat's wing and a human's hands
5 True/False questions
allopatric speciation → a hypothesis that speciation can result from selective pressures favoring different phenotypes within a population without geographic isolation as a factor
anagenesis → where two somewhat related species eventually form a new species
stabilizing selection → 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.
macroevolution → evolution of populations within a species
adaptation → a spontaneous change in the chemical structure of DNA
