Today I am somewhat puzzled over the fact that my vine produces two types of flowers, crinkled and uncrinkled ones. I have heard that MGs sometimes have split and unsplit flowers or single and double flowers on the same vine. I cannot fully comprehend that...I don't want any amateurish answers like, well, well, no snowflake is like the other because there must be a scientific explanation for what exactly is happening on the biological level (I am talking genes). I suppose this is a week analogy, but to me it's a bit like a hen laying white eggs on Monday, Tuesday, Wednesday and brown eggs for the rest of the week if you know what I mean. It's either brown eggs or white eggs...
