I'd also be more interested in some of the background on how the underlying mechanics work. Not sure if you mind sharing those publically. Is it genetic algorithms? Is there any sort of AI involved?
There isn't any AI or genetic algorithms involved. It's actually using genetics modelled on how genes in the real world operate (although on a a vastly simplified scale as there are only about 3 dozens genes as opposed to hundreds of thousands). Some phenotypes operate using dominant/recessive pairings, while others are quantitative, meaning that they can have values any where within a range of options. When you breed plants together it samples the two parents' genes and blends them, which is why your crosses are not always identical. There is also a chance for the crosses to mutate from the original parent, although the rate and scale of the possible mutations is greatly exaugurated.
