What is the relationship between the number of active genes and color of the skin

Skin color is polygenic trait meaning a lot of genes are significant in the expression of the trait. Such traits can have a multitude of variations showing continuous distribution because these non-epistatic genes have a cumulative effect on the skin color. The level of expression of these genes, majorly based on influence from the environment, will determine skin color. For example; the expression of the gene for melanin will be high in a person within the equator than in a person at the poles due to differences in sunlight exposure.

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.

i think it is dna, i'm not totally sure but i think it might be.
