Part A - Processes that contribute to genetic variation Meiosis guarantees that in a sexual life cycle, offspring will inherit one complete set of chromosomes (and their associated genes and traits) from each parent. The transmission of traits from parents to offspring is called heredity. Another important aspect of meiosis and the sexual life cycle is the role these processes play in contributing to genetic variation. Although offspring often resemble their parents, they are genetically different from both of their parents and from one another. The degree of variation may be tremendous. Which processes lead to genetic variation in sexually reproducing organisms

independent assortment, crossing over and random fertilization

Explanation:

There are three mechanisms by which sexual reproduction increases genetic variation in progeny. First, random fertilization is the process by which gametes randomly combine in order to increase the possibilities for genetic variation. Second, the independent assortment refers to the process by which pairs of homologous chromosomes independently separate from one another during meiosis. Finally, crossing over, also known as recombination, is the process by which two homologous chromosomes' non-sister chromatids can exchange genetic material during meiosis I (prophase I).
