GMO (genetically modified organism) - An organism whose DNA has been deliberately altered. Made possible by Recombinant DNA technology. Evolution - Change in a population or species over generations Microevolution - Change in allele frequencies in a population over generations. Macroevolution - Evolution at or above the species level Charles Darwin - Father of evolution Darwin's Theory of Evolution - Species living today descended from a single ancestral species. Two main components are ...

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...

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...

practice exams for the final Hp| Questions and Answers With Complete Verified Solutions, Updated 2024.

Adaptations - -are traits that an organism has that allow it to be better suited for its environment. Evolution - -is a change in inherited (genetic) features that occurs in populations and higher-level groups over time. Microevolution - -is a process that occurs within a single population as inherited traits become more or less common from one generation to the next. Macroevolution - -involves bigger changes that occur more slowly and cannot be directly observed in most cases. microevolu...
