Are alleles mixing between the populations? Is there evidence from DNA that alleles (variations of the same genes) are not freely mixing between the populations? Are some alleles more or less common in one population than another? Example: DNA analysis has shown that Australian blacktip sharks have variations in their DNA that are very rare in common blacktips, and vice versa. Evidence: Freely mixing Some No Consider the evidence together. Do you think alleles are mixing between the populations? mixing mixing N/A 1 2 3 4 5

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.
