Understanding Heritability in Animal Genetics and Breeding

Heritability is a crucial concept in animal genetics and breeding, indicating the proportion of total phenotypic variance attributed to genetic effects. It helps in predicting breeding values, assessing relationships between individuals, and guiding genetic determinations. Properties of heritability

Understanding Repeatability in Animal Genetics and Breeding

Repeatability in animal genetics assesses the correlation between repeated measurements of a trait on the same individuals. It partitions phenotypic variance into within-individual and between-individual components, aiding in estimating heritability, resemblance between relatives, and genetic determ

Understanding GWAS: A Brief Overview of Genetic Association Studies

GWAS, or Genome-Wide Association Studies, are a method used to map genes associated with traits or diseases by analyzing genetic markers throughout the genome. This process involves statistically testing the association between SNPs and traits using regression or chi-squared tests in a hypothesis-fr
