Yes, skin pigmentation or melanin production is controlled by multiple genes that vary by ethnicity. For example, while Southern Europeans and East Asians have similar skin tones, these represent two separate evolutions and mechanisms for the suppression of melanin production. Furthermore, there is more human genetic variety in Africa than the rest of the world combined.
Multiple genes are involved in determining skin color, but two of the main genes are MC1R and SLC24A5. These genes interact to produce variations in pigment levels that contribute to different skin tones. Genetic variations in these genes can lead to a wide range of skin colors observed in human populations.

How many pairs of genes control skin color?
3-6
What you inherit from your parents and these are codes for the traits you have?
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.
Who do you get your genes from?
You inherit your genes from your biological parents. Half of your genetic material comes from your mother and half from your father. Genes are passed down through generations and determine many traits, such as eye color, height, and susceptibility to certain diseases.
Do human cells have 46 genes?
No. The human cell has 23 chromosome pairs (total 46 chromosomes). Each chromosome has many genes.
How many chromosomes do human bodies have?
Humans typically have 46 chromosomes in each cell, with 23 pairs inherited from each parent. These chromosomes contain genes that carry genetic information and determine traits such as hair color, eye color, and height.
What is the difference between chromosomes and genes?
Chromosomes are structures within cells that contain DNA, while genes are specific segments of DNA that provide instructions for a particular trait. Chromosomes house many genes, along with other DNA sequences, and are inherited in pairs, one from each parent. Genes determine specific traits, such as eye color or blood type.

How many genes control eye color and fur in a white tiger?
One. That's it.
A typical gene contains the instructions for making?
It depends. Some genes determine a single trait all by themselves. Some genes work with other genes to make a trait. It takes several separate genes to determine how tall you will be. And then there are other genes that by themselves determine multiple traits. Each gene is the code for a peptide chain. Many of those become proteins.
How many total base pairs are in all the mammalian genes?
The exact number of base pairs in all mammalian genes is not known due to variations between species. However, the human genome contains approximately 3.2 billion base pairs. Mammalian genomes are generally similar in size to the human genome, so the total base pairs in all mammalian genes would be around this range.
How many genes are found on each of your chromosomes?
Humans have 22 pairs of autosomes and one pair of sex chromosomes (XX for females, XY for males). Each autosomal pair contains approximately 1,000-2,000 genes, while the X chromosome has around 1,500 genes and the Y chromosome has around 200 genes.
How both gene and the environment determine how tall a person will be?
A persons' genes do determine height but the environment also does. Many people without enough food as a child will not be as tall as their genes saw that they should be.
