What is a quantitative feature?
In genetics, the quantitative feature is the one that differs in its characteristics and expressions. The final expression is usually responsible for two or more genes along with the interactions of the environment. Such properties are described in numbers and may vary in grades. Most quantitative properties are continuous and often do not fall into any discrete categories. A study of the inheritance of such properties is called "quantitative genetics" and such phenotypes in humans include - but are not limited to - height, quotient intelligence (IQ) and blood pressure.
When scientists know the genotype or internal genetic code for a particular property, they can predict the resulting phenotypes or external characteristics of this characteristics. These are referred to as discontinuous features and are assigned discrete classes. However, not all properties fall neatly in a discrete classification, but instead are continuous and difficult to predict. Such types of properties are called quantitative features, Because is usually recorded as distribing of numbers.
Polygenic inheritance is the term used by scientists to describe the formation of quantitative feature. Grees that affect the value of quantitative characters are referred to as quantitative characters of characters (QTL). The formation of quantitative properties involves two or more genes contributing to phenotypic characteristics and often also involves interaction with the environment. For example, height in humans includes a number of genes; However, the final expression of the gene is affected by environmental factors, such as available nutrition. Rather than following a particular pattern, the properties differ along a continuous gradient, which is often illustrated on the bell curve.
Numbers and percentages are primary methods of documentation of quantitative properties. Numerical values of quantitative properties are often ordered from the highest deliver, and display a rather continuous order that is determined with a continuous gradient. The value of quantitative inLastiness often differs only in small, arbitrary amounts rather than fixed amounts. Therefore, most scientists assume continuous data rather than specific values or calculate when documenting quantitative properties. Scientists are trying to predict the scattering of quantitative properties to find the diameter of the distribution and display the range on the bell curve.
The expressions of quantitative properties occur in almost every organism, often especially in the life of plants and animals. In plants, examples include crop yield, color distribution and disease resistance. With the weight of animals and humans, the height, the ability of learning and even blood pressure, each expressed as a quantitative property.
