Not sure, maybe just look it up online, that should be effective.
The method is cross-pollination, achieved by utilizing parents with distinct traits.
Gregor Mendel studied pea plants and formulated the foundational principles of heredity. He coined the terms dominant and recessive to describe traits, based on his experiments. He practiced cross-pollination, which involves mating parents that exhibit different traits. For instance, he crossed a plant bearing green peas with another showcasing yellow peas (two contrasting traits) and examined the inheritance of these traits in subsequent generations.

Answer:
1. Mutation- enhances genetic variation
2. Selection- may raise, lower, or maintain genetic variation
3. Genetic drift- diminishes genetic variation.
4. Gene flow- could either enhance or reduce genetic variation
Explanation:
1. Mutation denotes changes in an organism's DNA. The mutations lead to new adaptive traits that evolve, which increases the genetic diversity of organisms.
2. Natural selection favors organisms best suited to their environment. Thus, selection can increase, decrease, or keep variation in a population steady.
3. Genetic drift occurs due to random events altering a population's gene pool. When this phenomenon transpires, the genetic variation within that population typically decreases.
4. Gene flow involves changes to the gene pool due to immigration and emigration. This factor can thus increase or decrease genetic variation.
