Xy Chromosome System
The XY chromosome system is a sex-determination mechanism found in dioecious cannabis plants, where males carry XY chromosomes and females carry XX chromosomes. This genetic framework governs the development of male (pollen-producing) and female (ovule-producing) reproductive organs. Understanding XY chromosome inheritance is foundational to breeding programs, as it directly influences the probability of male versus female offspring in controlled crosses. Cannabis breeders rely on this system to produce feminized seeds, maintain breeding lines, and selectively develop cultivars with desired traits linked to sex chromosomes or sex-influenced expression patterns.

Cannabis breeders rely on this system to produce feminized seeds, maintain breeding lines, and selectively develop cultivars with desired traits linked to sex chromosomes or sex-influenced expression patterns.
Breeders working with XY chromosome systems employ sex selection and sex reversal techniques to control offspring ratios and create breeding stock. Knowledge of XY inheritance helps predictably generate female-only seed lines and stabilize traits expressed differentially between sexes.
