Random fertilization is the concept that each sperm and egg combination is unique due to independent assortment and crossing over during meiosis, leading to a vast number of potential genetic combinations in offspring.
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.
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.
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.
