Genetics is the study of heredity and variations in organisms due to genes.
Think about baking cookies using your grandma's recipe. The recipe (genes) you inherited from your grandma determines what kind of cookies you'll end up with (traits). But how you mix those ingredients or maybe add some extras can create slight variations each time you bake them - just like how environment interacts with our genes leading to individual differences.
Genotype: This refers to an individual's complete set of genes. It's like having all possible recipes for making cookies but not knowing which ones will actually be baked.
Phenotype: This is an observable trait or characteristic resulting from genotype interacting with environment - it’s what kind of cookie you actually get!
Allele: An allele is a variant form of a gene; it's like a different version of the same recipe.
