What is micro-evolution? - Changes in allele frequencies within populations, often associated with adaptation, can be measured from one generation to the next "small changes" What is macro-evolution? - Major changes in the history of life, origin of new species, generates biological diversity "big changes" What is a species? - a group of populations whose members have the potential to interbreed with one another in nature to produce fertile offspring What is allopatric speciation? - ...

bio 181 exam 1 (kosal)Compare and contrast the different mechanisms of speciation (allopatric, sympatric, parapatric, peripatric). - correct answer -Allopatric speciation takes place when populations are geographically isolated. Volcano explodes and populations are divided. -Sympatric occurs without geographic isolation. Occurs through the process of polyploidy: producing individuals with more than two sets of chromosomes. It is a genetic change within a population. -Parapatric speciation ...

Molecular phylogeny It compares the structure of a particular molecule from different organisms to discover their degree of evolutionary relation. Somatic cell A cell in an organism which isn't a gamete. DNA Deoxyribose nucleic acid. Carries the genetic information for cells and some viruses. mRNA Messenger ribose nucleic acid (single stranded). The product of transcription. Speciation The process through which a species is created Sympatric Due to reproductive isolation. ...

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...
