Here's a nit to pick, which I only do because I found it interesting personally.

What you say is true unless the plant reproduces apomictically, in which case
the child plant grown from seed is genetically identical to the parent. This is
the case for many Rowans, which is the context in which I found out about
this fascinating mechanism.

No quibble at all with what you said visavis the lemon, of course.
