Heritability Coefficient Calculator

Aspect	Explanation
Definition	The heritability coefficient (h²) measures the proportion of phenotypic variance due to genetics.
Range	Heritability values range from 0 to 1, where 0 indicates no genetic influence and 1 indicates full genetic influence.
Interpretation	Higher h² values suggest genetics play a larger role in trait variation, while lower values suggest environmental factors are more influential.
Calculation	h² = VG / VP, where VG is the genetic variance and VP is the total phenotypic variance.
Twin Studies	Twin studies compare monozygotic (identical) and dizygotic (fraternal) twins to estimate h².
Family Studies	Family studies analyze trait similarity within families to estimate genetic influence.
Adoption Studies	Adoption studies compare adopted children to their biological and adoptive parents to estimate h².
SNP-Based Heritability	SNP-based heritability uses genetic markers (SNPs) to estimate h² across large populations.
Interpretation Challenges	Heritability estimates vary with population, environment, and measurement methods.
Not Individual Prediction	Heritability is a population-level measure and doesn’t predict trait inheritance in individuals.
Complex Traits	Heritability is complex and influenced by genetics, environment, gene-environment interactions, and more.
Trait Variability	Low h² doesn’t mean a trait is unimportant, as environmental factors can still play a significant role.
Misunderstandings	High h² doesn’t mean a trait is unchangeable; interventions can still impact trait expression.
Different Traits	Different traits (height, intelligence, personality) have different heritability coefficients.
Evolutionary Implications	Heritability influences the response to selection in breeding and evolutionary processes.
