Gametes:These are the reproductive cells (sperm in males, eggs in females) that carry genetic information. They're like the individual ingredients for our cake.
Meiosis:This is the process by which gametes are produced, involving two rounds of cell division that result in four daughter cells each with half the number of chromosomes as the parent cell. It's like preparing and measuring out your ingredients before you start baking.
Genetic Variation:This refers to differences in genes between individuals within a population. It's like having different flavors or types of cakes because not all cakes (offspring) will be exactly alike due to variations in their 'ingredients' (genes).
