Biology 1 Assessment 3 Miller, Timia 00 26 of 40 21 22 23 24 25 26 27 28 29 30 Polyploid plants form as a result of a beneficial mutation that often makes them larger and stronger than diploid plants. These plants form when a complete set of chromosomes fails to separate during meiosis creating plants with extra chromosomes. What type of mutation has this result? O frameshift O nondisjunction substitution O translocation

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.
