Alleles are matching genes inherited from each parent, forming pairs that can be identical or slightly different. These variations influence traits like eye color, health risks, and reactions to medications. Dominant alleles can override recessive ones, affecting observable traits. Our genotype, the genetic makeup, is determined by these allele pairs, impacting our physical appearance and daily life.
