This video is about the methods to estimate heritability. Heritability can be estimated using different statistical methods like regression, correlation and ANOVA. In this video, I have describes the following methods:
Methods to estimate broad sense heritability
1. Monozygotic and Dizygotic twin data or Identical and fraternal tin data
Methods to Estimate Narrow Sense Heritability
1. Offspring-Parent Regression
i) Regression of offspring on one parent
ii) Regression of offspring on mid parent
2. Correlation between relatives
i) Correlation between parent and offspring
ii) Correlation between sibs (full sibs or half-sibs)
3. Analysis of Variance (ANOVA) or Intraclass Correlation
i) Intraclass correlation between full sibs
ii) Intraclass correlation between half sibs
4. Restricted Maximum Likelihood (REML) Method
Software e.g. WOMBAT, ASREML, SAS, BLUPF90
