A true autoflower is homozygous recessive[10] for the day neutral genetics. Therefore, most crosses between classical photoperiod/short-day strains and autoflowers produce few or no autoflower progeny in the F1 generation. Regardless of whether the F1 generation produces autoflowering plants, the higher performing and similar plants need to be recrossed. This F2 generation will contain approximately 25% of homozygous recessive plants which are autoflowering. Still the few autoflowers produced are not always stable and may require further stabilization. Further complexities with stabilizing autoflowers has previously led to non autoflowering and low quality strains making it into the market.
