Blimey!

Pollination ping!

[The Comedian]

Probably direct stamen to pistil cross pollination...

Hey, watch the language pal. This is a family forum.

Frowning takes 68 muscles.
Smiling takes 6.
Pulling this trigger takes 2.
I'm lazy.

When you’re an angiosperm you have to...............

Meyer Lemon bump... best, biggest, easiest to grow, for me.

Reminds me of those goats that just drop over.

[Red Badger]

You must be a gymnosperm............

I was going to say something about wood, but decided against it.

While this may not be an example of evolution through natural selection of genetic variation, it is an example of evolution through human selection (and creation) of genetic variation.

The model that they used to derive this ancestry is the same model used to show common ancestry of closely related species.

Cross pollination also doesn't “mix genes” (i.e. swap out genes along the chromosome to produce reproductive cells).

Plants are strange in that most successful crossbreeds do not have one half of the DNA of their mother and half of the DNA of their father, but ALL of the DNA of their mother and ALL of the DNA of their father. This allows them to avoid the infertility often associated with crossbreeds; for example a Tigon and/or a Lyger has problems producing viable reproductive cells because when it tries to ‘mix and match’ mom and dads genes along the chromosome, the differences between the Lion chromosome and the Tiger chromosome can often make a mess of things.

We’ll just let it be in the “cone” of silence............

[Red Badger]

... and to point to how long ago the species diverged from some point. The plants in this case still have wild ancestors available.........

Most welcome! This stuff fascinates me!

Proof that environmentalist tree huggers have sex with trees.....

The evidence also confirmed that bergamot was a hybrid of sour orange and citron, with sour orange as the maternal parent and citron as the paternal parent.

Well, learn something new everyday.

Wild bergamot or Bee balm[1] (Monarda fistulosa) is a wild flower native to North America.[2] This plant is often used as honey plant, medicinal plant, and ornamental plant.[3]

Grows all over the place here.

THIS is what I should have been looking for:

Bergamot orange, citrus fruit used in Earl Grey tea. ... The bergamot orange is unrelated to the herbs of the same name, Monarda didyma and Monarda fistulosa, which are in the mint family.

I KNEW I was doing something wrong!

Maybe just cross pollination?
