This plant most likely came from another leafy vegetable. An offspring that could come from the seeds could be a cabbage. I predict this because it's leafy, green and large. I could predict what the offspring will look like by looking at the current traits of the parent plants. They would acquire these traits by meiosis. Meiosis splits the number of chromosomes in half from each parent, giving an equal amount of chromosomes from each parent to the offspring. The parent plants will pass on traits during the process of the production of gametes. They may look like them, but no plant offspring will ever look exactly alike. When creating an offspring, the results can't be the same because of different sets of chromosomes ex AA + BB = AB, a completely new plant. The most possible explanation to this is through adaption and manual selection.
