A new service now offered @ DigiPath Labs: plant sexing
Cannabis is a dioecious plant species. Dioecious plants have the male and female reproductive structures on separate plants. Male plants have one X and one Y chromosome, while females have two X chromosomes. The Y chromosome differential provides for a rapid molecular means for plant sexing after the appearance of the first cotyledon, allowing cannabis cultivators to focus on development of only female flowers rich in cannabinoids.
