Heritability obesity
Witryna29 sty 2015 · Strong heritability estimates for obesity and body mass index (BMI) indicate the role of genetics supported by twin and family studies. In twin studies, heritability estimates for BMI are between 20 and 86 % with an average of about 50 % in children and adults [13–16]. The definition of heritability is a measure of the fraction … Witryna24 sty 2024 · Whilst many genes/loci confer susceptibility to obesity, little is known about the genetic architecture of healthy thinness.
