1. Species that reproduce sexually have an advantage over those that reproduce asexually when external conditions change. This is how organisms have become adapted to their environment over time. – Describe the difference between sexual and asexual reproduction in terms of the genetic makeup of the offspring. 9 8 10 20

2. Sexual reproduction uses genetic material from two parents to produce offspring with unique sets of traits. Asexual reproduction produces offspring with the same combination of traits as the parent.

3. Explain why a species that reproduces sexually might be more likely to survive a sudden environmental change than a species that reproduces asexually. 9 8 10 20

4. In a changing environment, a sexually reproducing species is likely to have a diverse set of individuals in its population. Although some individuals may not survive, others may have a combination of traits that helps them to survive
