No, a foal from a grey horse does not necessarily have to become grey. The grey color in horses is a result of a dominant gene that causes the horse's coat to lighten over time. However, the foal's color is determined by the combination of genes from both its parents, so if the other parent carries a different color gene, the foal may inherit that color instead. Additionally, some grey horses may produce non-grey offspring if they carry other color genes that are passed on to the foal. **

No, a dun horse cannot become a grey horse. Dun and grey are two distinct coat colors determined by genetics. Dun horses have a specific dilution gene that gives them their characteristic coat color, while grey horses have a gene that causes their coat to progressively lighten with age. Once a horse is born with a dun coat, it will not change to a grey coat over time. **

The grey star on a horse refers to a small patch of white or light-colored hair on the horse's forehead.
