The gray gene causes color changes with chestnut foals that carry the gray allele often darkening some hair as other hair turns white.
Dark bay, black or brown horses don't seen to have much of a pigment shift in the colored portion of their hair coat.

There are two base colour gene for horses what are they?
For Howrse Black and Red
The gene which causes chestnut horses to be palomino or cremello or bay horses to become buckskin or cremello is called what?
The cream gene Cr. Bay horses that are homozygous for cream are perlinos as opposed to cremellos.
The gene which causes chestnut horses to become palomino or cremello?
The common term for the gene/allele that causes a genetically chestnut horse to be a palomino or cremello is Dilution. A palomino has one of these alleles, a cremello has two.
What is the gene in horses called that causes pallomeno to become cremello?
That would be the cream gene. The cream gene dilutes darker colors to lighter colors, I.E. Chestnut= palomino. To get a palomino the horse must receive one copy of the gene. To further change the palomino back into a Cremello, the horse needs two copies of the cream gene. (Double dilute.)
What causes a frequency in a population to change after each generation?
Gene mutation causes the phenotype frequency in a population to change after each generation.
What term refers to a factor that causes a change in a gene or chromosome?
mutation
What does dappled gray horses mean?
A dappled horse is like a horse with patches or spots of colour on it. Some horses are just brown, grey, black etc, dapple is just another colour variation. The horse would usually be white with grey spots/patches on it.Usually found on the horses hind or back legs.
Are Albino and Cremello horses the same?
No.... albino horses have no pigmentation at all, and this often makes their eyes red, and they are normally white. Cremello horses are like more a creamy colour, and have blue eyes( generally) There has never been a verified albino horse. The gene is though to not exist in horses.
What is the gene that turns horses from bay to buckskin?
The cream gene.
What factor causes the greatest change in gene pools?
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.
In cystic fibrosis a change in a single gene causes the protein called CFTR to?
fold improperly
Why do some people have the same skin colour as their parent and others skin colour different from their parent?
it depends on your gene. there are dominant and recessive gene present. and for skin colour, bright colour are dominant over dark colour. if the both the parent are bright skin colour but the children is dark skin colour. there are possibilities where the recessive gene present in one or both parent. under certain circumstances the recessive gene will show its trait instead of the dominant gene. that's why some parent skin colour is different from the childrens' skin colour
