The hypothesis of punctuated equilibrium was based on what model for speciation? - peripatetic speciation What is true microevolution? - it is the kind of evolution that can change the relative abundance of a particular allele in a gene pool over the course of generations A relatively small number of Amish immigrants came to this country in the 1700's. They have since greatly increased their number while remaining largely segregated from the rest of the population. Polydactyly (having ...

Evolution - Answer-Change in the inherited traits in a population of organisms over time. Ecology - Answer-How organisms interact with each other and the environment Natural selection - Answer-A natural process resulting in the evolution of organisms best adapted to the environment. Theory of evolution - Answer-Created by Charles Darwin, organisms pass on their DNA to their offspring; avoiding close relatives for more variety. Microeveolution - Answer-The change in the inherited traits in ...

Microevolution - correct answer change in gene frequency in a population Macroevolution - correct answer evolution builds overtime; looked at from outside the species level Meiosis - correct answer cell division in which alleles are spread apart; produces gametes, four haploid cells Mitosis - correct answer "basic" eukaryotic division; cell division that makes identical copies; duplicated DNA is split Binary Fission - correct answer happens in prokaryotes; divides into tw...

BIO 107 Study Guide QUESTIONS WITH DETAILED VERIFIED ANSWERS | A+ GRADE ASSURED Microevolution Evolutionary change below the species level; Change in allele frequencies over generations. It is called micro evolution because it focuses on evolution in population, which is the smallest scale. (individuals do not evolve.) 3 mechanisms that cause allele change Natural seletion, genetic drift( chance events that alter allele frequencies), and gene flow (the transfer of alleles between populatio...

What is microevolution? - The change in allele frequencies that occurs over time within a population. What is macroevolution? - Major evolutionary changes over time, the origin of new types of organisms from previously existing, but different, ancestral types. What is a species? - A group of populations whose members possess similar anatomical characteristics and have the ability to interbreed. What is allopatric speciation? - The formation of a new species in populations that are geographi...
