Evolution by Natural Selection - correct answer The process in which the
environment determines which individuals survive and reproduce
Artificial Selection on Animals - correct answer The process in which humans
determine which individuals breed, typically with a preconceived set of traits in
mind.
Natural Selection - correct answer All species produce an excess number of
offspring. Only those offspring with the fittest genotypes will pass on their genes to
the next generation-not random because environment determining traits that are
most successful
Fitness - correct answer An individual's ability to survive and reproduce
Adaptation - correct answer A trait that improves an individual's fitness
evolutionary processes that are random - correct answer 1. mutation
2. Gene flow
3. Genetic Drift
4. Bottleneck effect
5. Founder Effect
Evolution - correct answer A change in the genetic composition of a population over
time.
Gene Flow - correct answer The process by which individuals move from one
population to another and thereby alter the genetic composition of both populations
Genetic Drift - correct answer A change in the genetic composition of a population
over time as a result of random mating
