Answer to Question #165598 in Genetics for Shahid ali

Question

What is a frequency distribution? Explain how the graph is made for a quantitative trait that is continuous.

Answer 1

The continuous variation for complex traits is caused by genetic complexity and environmental sensitivity. Polygenic traits are usually expressed as continuous data, for which a statistical distribution is best graphically expressed as a normal distribution of possible theoretical values of the measurements - frequency distribution. This graph represents the frequency (number) of a certain trait showing it as a continuum. It describes the distribution of individuals among categories by their frequencies.
