quantitative genetics

Quantitative genetics studies how inherited genes influence traits that vary in degree, such as height or weight. Unlike traits determined by a single gene, these traits are shaped by many genes working together, along with environmental factors. It helps us understand how much of the variation in a trait is due to genetics versus environment, informing areas like breeding and conservation. By analyzing the genetic contribution, quantitative genetics predicts how traits may change over generations and guides efforts to improve desirable characteristics in plants, animals, or humans.
