Which statement below best describes the difference between quantitative and discrete traits:

(a) discrete traits result from the action of many genes, while quantitative traits involve a single genetic locus

(b) discrete traits cannot be categorized into a few distinct phenotypes

(c) quantitative traits result from the action of many genes, while discrete traits involve a single genetic locus

(d) quantitative traits can be easily categorized into a few distinct phenotypes

Solutions

Expert Solution

The statement that best describes the difference between quantitative and discrete traits is:

(c) quantitative traits result from the action of many genes, while discrete traits involve a single genetic locus

Explanation- quantitative traits also known as continuous traits form a spectrum of phenotypes that blend imperceptively from one type to another.This trait is a measurable phenotype that depends on the cumulative actions of many genes and the environment. These traits can vary among individuals, over a range, to produce a continuous distribution of phenotypes. They fail to fit in separate phenotypic classes.

Where as qualitative traits or discrete traits are under the genetic control of small number of genes, often only one, with little or no environmental modification to obscure the gene effects. These discrete traits can be easily classified into distinct phenotypic categories.

Ps- An upvote would be highly appreciated
