Independent Assortment:This refers to how different genes independently separate from one another when reproductive cells develop. It's like shuffling a deck of cards - each shuffle results in a different arrangement.
Crossing Over:This is the exchange of genetic material between homologous chromosomes during meiosis, which leads to new combinations of genes. Imagine swapping stickers with your friends; you all start with similar collections but end up with unique assortments.
Genetic Variation:This term describes diversity in gene frequencies, which can be caused by mutation, interbreeding, or environmental changes. It's like having various flavors at an ice cream shop - they all come from basic ingredients but are mixed differently for variety.
