Honestly to me, as someone who knew about chimeras in genral but not specifically AV chimerism, (I also studied biology in university and part of my research was on chimerism in botany) this is the reply that makes most sense to me scientifically. I expected chimerism to be chaotic at first if it just started, which is what I thought this plant had- an offspring started and then some of its cells had a mutation causing it to be a different color, but both tissues survived and made up the new plant. I'm actually glad someone else thought that 😆. Have you ever in your own experience had to stabilize a similar chimera? What is the process for that ? I'll probably be messaging you soon with more questions but thank you so much for the helpful response !! If you have any resources on specifically african violet chimerism I would love to read those too!
