About genetics
Genetics is the study of genes and how traits, like eye color, are passed from parents to children.
Geneticists study how alleles are inherited, how variation arises through mutation, and how genotype and environment together shape traits.
From Mendelian ratios to genome-wide variation, genetics links differences in DNA sequence to traits, disease and evolution.
