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.

How many pairs of genes control skin color?
3-6
Do human cells have 46 genes?
No. The human cell has 23 chromosome pairs (total 46 chromosomes). Each chromosome has many genes.
Do humans have 46 genes?
No. The human cell has 23 chromosome pairs (total 46 chromosomes). Each chromosome has many genes.
How many genes do cells obtain?
The number of genes varies from chromosome to chromosome and the number of chromosomes varies from species to species (from as few as 1 single chromosome per cell to as many 30,000 chromosome pairs per cell). Human cells have 23 chromosome pairs per cell.
What kind of trait is present when many different genes different genes control a single trait such as skin color?
epistasis
How many pairs of genes control skin color?
3-6
How many total base pairs are in all the mammalian genes?
3,000,000,000,
Do human cells have 46 genes?
No. The human cell has 23 chromosome pairs (total 46 chromosomes). Each chromosome has many genes.
How many genes are found on each of your chromosomes?
Humans have 46 chromosomes (23 pairs), chromosomes are long strands of genes, and since the chromosomes come in pairs, so do the genes. There are 25,000 genes in the entire human genome, and since the haploid chromosome number is 23, there are about 100's of genes on the shorter chromosomes and approximately thousands on the longer chromsomes.
Do humans have 46 genes?
No. The human cell has 23 chromosome pairs (total 46 chromosomes). Each chromosome has many genes.
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 genes control eye color and fur in a white tiger?
One. That's it.
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.
How many genes do cells obtain?
The number of genes varies from chromosome to chromosome and the number of chromosomes varies from species to species (from as few as 1 single chromosome per cell to as many 30,000 chromosome pairs per cell). Human cells have 23 chromosome pairs per cell.
How many genes minimum is needed to determine a trait?
The least number is 2, however this is very rare. Most traits require many genes to produce a trait.
What kind of trait is present when many different genes different genes control a single trait such as skin color?
epistasis
How many genes are there in a fruit fly?
Each cell of a fruit fly contains 13,601 genes.
