One study found that 80% of the offspring of two obese parents were obese, in contrast to less than 10% of the offspring of two parents who were of normal weight. [ 30 ] The thrifty gene hypothesis postulates that due to dietary scarcity during human evolution people are prone to obesity.
A genetic correlation is to be contrasted with environmental correlation between the environments affecting two traits (e.g. if poor nutrition in a household caused both lower IQ and height); a genetic correlation between two traits can contribute to the observed correlation between two traits, but genetic correlations can also be opposite ...
People in the field work toward developing an understanding of how the whole body responds to a food via systems biology, as well as single gene/single food compound relationships. [1] [2] Nutritional genomics or Nutrigenomics is the relation between food and inherited genes, it was first expressed in 2001. [3] [4]

The dual intervention point model posits that rather than a body weight set point, there is a set range for body weight. Under this model, active compensation happens only outside of upper and lower intervention points, and for weights within the set range, environmental factors would have a strong effect on body weight since there would only ...
The size of a tomato is one example of a complex trait. Complex traits are phenotypes that are controlled by two or more genes and do not follow Mendel's Law of Dominance. They may have a range of expression which is typically continuous. Both environmental and genetic factors often impact the variation in expression.
Many of us believe we are masters of own destiny, but new research is revealing the extent to which our behavior is influenced by our genes. It’s now possible to decipher our individual genetic ...
