👉 In genetic terminology, a "genitor" is a gene that is involved in the formation of a cell or tissue. It is typically found on the X chromosome and codes for a protein or hormone that is essential for the development of the corresponding tissue. For example, if a person has two genes that code for a specific type of muscle fiber (e.g., one gene for fast-twitch fibers and another for slow-twitch fibers), then they are likely to have a "genitor" gene
