Traits are shaped by interactions between genetic variation and environmental conditions. Learn how genes, environment, epigenetics, gene-environment interactions, heritability, and phenotypic plasticity contribute to variation in complex traits.
Penetrance and expressivity explain why individuals carrying the same genetic variant can show different phenotypes. Learn about incomplete penetrance, variable expressivity, genetic modifiers, environmental influences, and genotype-phenotype relationships.
Pleiotropy occurs when a single gene or genetic variant influences multiple phenotypic traits. Learn how pleiotropic genes affect biological pathways, development, human genetic disorders, complex traits, and evolution.
