Examples of quantitative traits include height, weight, and blood pressure. There is no single gene for any of these traits, instead it is generally believed that continuous variation in a trait such as blood pressure is partly due to DNA sequence variations at multiple genes, or loci .May 29, 2018
Is weight a genetic trait?
Genes give the body instructions for responding to changes in its environment. Studies of resemblances and differences among family members, twins, and adoptees offer indirect scientific evidence that a sizable portion of the variation in weight among adults is due to genetic factors.
What kind of trait is weight?
BODY weight is a composite trait comprising the weights of lean (protein) and fat compounds as well as those of bones and body fluids. As a quantitative trait, body weight reflects the effect of a complex net of gene actions under the influence of the environment.
What are genetic traits in a person?
Trait is a specific characteristic of an individual. For example, their hair color or their blood type. Traits are determined by genes, and also they are determined by the interaction with the environment with genes. And remember that genes are the messages in our DNA that define individual characteristics.
What is a simple genetic trait?
Simply-inherited traits are those where one or just a few genes control the phenotype. Coat color, horned/polled status, and many genetic conditions fall under the category of simply-inherited traits.
Is obesity genetic or behavioral?
Genetics. Genetics can directly cause obesity in specific disorders such as Bardet-Biedl syndrome and Prader-Willi syndrome. However genes do not always predict future health. Genes and behavior may both be needed for a person to be overweight.
What is genetic weight?
Genetic Weight. Your genes influence not just your weight, but also the impact of different healthy habits. Your Wellness Result. Jamie, your genes predispose you to weigh about average. This doesn't mean your weight will definitely be average.
Is a persons weight a single genetic trait a qualitative trait or quantitative trait?
Examples of quantitative traits include height, weight, and blood pressure. There is no single gene for any of these traits, instead it is generally believed that continuous variation in a trait such as blood pressure is partly due to DNA sequence variations at multiple genes, or loci .
Is weight and height genetic?
For most individuals, though, height is controlled largely by a combination of genetic variants that each have more modest effects on height, plus a smaller contribution from environmental factors (such as nutrition). More than 700 such gene variants have been discovered and many more are expected to be identified.
