Here's a breakdown:
* Gene: A segment of DNA that provides instructions for building a particular protein or RNA molecule.
* Allele: A specific version of a gene. For example, the gene for eye color might have an allele for brown eyes and an allele for blue eyes.
* Trait: A characteristic that can vary among individuals, like eye color, height, or disease susceptibility.
Each individual inherits two alleles for each gene, one from each parent. These alleles can be the same (homozygous) or different (heterozygous). The combination of alleles an individual possesses determines their phenotype, or observable characteristics.
