What color gene is most dominant in horses?

Bay is the dominant phenotype (the physical expression of a genetic trait) between the two, and its genotype is expressed by either E/Aa or E/AA. Black is the recessive coat color, meaning it is always homozygous and expressed asE/aa. All other equine coat colors and patterns stem from these base coat colors.

Does a grey horse have to have a grey parent?
