One. That's it.
YesYes. Those types of genes are called polygenic traits.
Polygenic trait, where multiple genes contribute to the expression of a single trait like skin color. Each gene may have a small effect on the trait, and their combined influence results in a continuous range of variation.
Wheat grain color is primarily influenced by a small number of gene pairs, particularly two major genes: the P gene and the C gene, which determine whether the grain is red or white. Additionally, several minor genes also contribute to the variation in color. Overall, while the primary genes are few, the total number of gene pairs involved in determining wheat grain color can be more extensive due to the influence of these minor genes and their interactions.
You inherit genes from your parents, which contain the instructions for traits such as hair color, eye color, and height. These genes are passed down through generations and determine many of your physical and biological characteristics.

The answer is simple, genes are inherited and traits are your own uniqueness, genes will have an influence on your traits, so if you are a loud person, that will be one of your traits, and if a parent is a loud person, you will have most likely inherited that gene from them, so the answer is one gene controls many traits because the gene was there first
