The commonest system of genotypically controlled sex determination depends on the segregation of a difference at meiosis. This system may operate at the haploid level, as in many algae and bryophytes, or at the diploid level. From the standpoint of the meiotic system, the sporophytic phase in types with genotypically controlled haploid dioecism is comparable with the heterogametic sex of types showing diploid dioecism (Lewis 1961).
