Have you ever wondered about the traits that you see in the violet you're entering in the show? How did the hybridizer get the Geneva Edge on that cultivar? You know, the plant that has those pretty purple flowers with the striking white edge. Are the "girl foliage" style leaves more common than the "boy" style?
Here's a brief and basic chart, graciously provided by Dr. Jeff Smith, that gives us an overview of the basic traits that are dominant and recessive in the African violet! I'd like to thank Dr. Smith for this information and Clay Anderson for the great cartoon that so nicely fits with our subject! Ever notice how "plant people" are the best when it comes to sharing information and help with regards to our horticultural hobby? Remember to send some comments and let these folks know that you appreciate their contributions!!!

Maternal Traits: Tommie Lou and Crown Variegation, Lilian Jarrett Variegation (in part). Offspring will only show the trait if the seed parent had the trait.
The following list is the expected results from genetic crosses with dominant and recessive traits:
1. Dominant X Dominant
Result - all Dominant offspring or 75% Dominant and 25% Recessive
2. Dominant X Recessive
Result - all Dominant offspring or 50% Dominant and 50% Recessive
3. Recessive X Recessive
Result - all Recessive offspring
The percentages given for the offspring are approximate values. The actual results you get may vary considerably from these percentages.
