In a population of lizards, half of the individuals are yellow and half are blue. Color is genetically determined. Which of the following scenarios could result in evolution by genetic drift? O A disease indiscriminately reduces the population by 90%. Females preferentially mate with blue individuals. Yellow individuals from a nearby population join the population. Birds are better able to see and therefor prey on blue lizards.

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.
