nutrition and gene factors
The base color is black/red factors, controlled by the Extension gene. A horse with one or two copies of the Extension gene (Ee or EE) will have black factors. A horse with no copies of the Extension gene (ee) will be chestnut.The Agouti gene acts on the Extension gene by limiting where the black factors are displayed, into points such as the legs, mane, tail, muzzle, and ears. A horse with at least one copy of the Extension gene that doesn't not have a copy of the Agouti gene will be black, provided that no other gene modify the color. One or two copies of the Agouti gene in combination with the Extension gene will result in a bay horse. A chestnut horse (no copies of the Extension gene) can have copies of the Agouti gene, but it will not affect the horse's color, as the horse has no black factors for the Agouti gene to limit.
Transcription factors can regulate gene expression
transcription factors.
There are a number of factors which have kept gene therapy from becoming an effective treatment for genetic disease. The viral rectors are the main problems which might make gene therapy to cause diseases.
alleles
A gene is a part of the chromosome what is linked to your DNA it carries the proteins which make you, you! Factors that control traits.
Environmental factors cause the greatest change in gene pools. some of these factors are radiation,pollution,food supply,population,predators,and camouflage. Of these factors the most important to today's gene pool is radiation because it causes mutation in the chromosomes and can completely change an organism.
