@KS_razerback pointed out the chimera fruit and asked if it is the same as the striped fruit.
Chimera fruit is very rare and has two distinguishable sides to the fruit whereas striped fruit has some overlap and is less defined. Striped pears - research is needed - #12 by KS_razerback
My understanding is they are not exactly the same.
Chimeras are where two different genetic cell lines are propagating often in a single leaf, stem, fruit, or even an entire organism. Striped fruit is an entirely different mechanism. It is caused by a single gene which can flip back and forth between two states.
Ok, thanks, that makes more sense on how to tell chimera striping versus genetic trait striping.
It’s a very fine line splitting those hairs between definitions on that topic. Check out this Red St. Lawrence Apple. That is a very beautiful striped apple! Red St. Lawrence Apple - Fedco Seeds
Mutations/sports traits are inheritable to offspring, right?
Some mutations are a result of methylation, transposons, or other genetic events that are not permanent. When a cell undergoes meiosis (splitting for reproduction), often the DNA will change such as from transposons. When this occurs, a mutation may be changed in ways that make it no longer expressed. In other words, some mutations are not inheritable.
My old red Bartlett tree has a small limb sport that produces striped red and green, or yellow depending on the ripeness, pears.
Its small and low on the tree so doesn’t do anything but fruit. No new vegetative wood. Im thinking about a concerted effort to get it to produce some usable scions so i can make a new tree.
Could be. what do you think? just remove the fruit or maybe something more drastic?
Here it is harvest time for the Red Bartlett and this year there is no striping! Just looks like a std Bartlett.
First pics are of the reds…
It may have been this way for a couple years, (no stripes) i haven’t been paying much attention.

Prague Citsuma (citrus) a periclinal chimera of a satsuma and a trifolate orange, but not in the fruit itself. Instead, its fruit are entirely that of a sweet satsuma, and it’s leaves and stem are of a trifolate, making it hardy to around zone 7b-a but still tasty.
