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.

Question

In Dr. Kettlewell's peppered moth experiment, what was the DV?

Question 4 options:

	The birds
	The phenotype color of the moth in relation to the color of the tree
	The moths
	How many moths were eaten of each color phenotype

Definition Definition Observable physical traits or characteristics of an organism, which are determined by its genetic makeup (genotype) as well as environmental factors. These traits can include anything from eye color or height to behavior or disease susceptibility. Understanding an organism's phenotype is important in fields such as genetics, medicine, and ecology.
