Evolution and Genetics Quiz

• Microevolution involves changes within a population's gene pool, while macroevolution involves large-scale changes resulting in the formation of new species. (correct)
• Microevolution leads to the emergence of new traits, while macroevolution leads to the extinction of species.
• Microevolution only involves changes in allele frequencies, while macroevolution involves changes at the species level.
• Microevolution occurs over short timescales, while macroevolution occurs over long geological timescales.

• It defines a species based on shared physical characteristics and traits.
• It classifies species according to their genetic similarity and relatedness.
• It categorizes species based on their ecological niche and habitat preferences.
• It defines a species as a group of organisms that can interbreed and produce viable offspring. (correct)

• It is the reduced viability or fertility of hybrid offspring in subsequent generations. (correct)
• It indicates the genetic compatibility between two different species.
• It refers to the initial sterility of hybrid offspring between two different species.
• It describes the successful adaptation of hybrids to new environments.
