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

What is required for sympatric speciation to occur?

A. Continuous gene flow between different populations

B. Geographic separation of populations

C. Two populations that are different begin to reproduce and create hybrids

D. Emergence of a reproductive barrier

Definition Definition Process by which new species arise. This occurs when populations of a species become isolated and diverge, developing unique traits through natural selection, genetic drift, or other mechanisms. Over time, these differences accumulate until the populations can no longer interbreed and are considered separate species.

Parapatric isolation 1. It occurs when the groups that evolved to be separate species are geographic neighbors. 2. The differences in reproductive organs prevent successful interbreeding 3. The different groups may not be reproductively mature at the same season, or month or year. agoXMO 4.
