Final answer:
Quantitative traits are controlled by multiple genes and show continuous variation. Their inheritance is influenced by genetic and environmental factors.
Step-by-step explanation:
In biology, quantitative traits are those traits that show continuous variation and are controlled by multiple genes. These traits are typically measured on a numerical scale, such as height or weight. Examples of quantitative traits include height, weight, skin color, and eye color.
The inheritance of quantitative traits is controlled by a combination of genetic and environmental factors. While multiple genes contribute to the phenotype, each gene may have a small effect. Thus, the inheritance of these traits follows a complex pattern and is influenced by both genetic and environmental interactions.
For example, height is a polygenic trait that is influenced by various genes. Each gene may contribute a small effect, and the combined effect of these genes determines the overall height of an individual. Environmental factors, such as nutrition and exercise, can also influence height.
