Frequency of Occurrence 3 Lobe Seedlings?

Wondering if this is a common occurrence?

A tiny 4 week old seedling is on its fifth set of 3 lob leaves. It looks like a rose, except tiny, and closely spaced leaf sets.

That is unless its a cross between Prairie Dawn and a strawberry (l claim a genetic first if true) …… its not likely a pure strawberry caused by contamination as leaves are not crenulated or “rough”. If it is, l am in line for a “Golden Raspberry” award in hybridizing … a light moment for your day.

This is pretty standard for rose seedlings. The mature foliage will develop more leaflets.

R. laevigata is the only rose that I know of to have only 3 leaflets on mature leaves.

To further cement that 3 leaflets per leaf is common in seedlings (new learning for me from the intense world of micro observations when watching hoped for successful crossings develop); during morning gardens tour l found a seedling (volunteer) that is full of three leafs and maybe “ 3 inches high” among the lilies of the valley and bergina (hardy elephant ears).

No idea what it is. But leaf geometry elongated, seat of the pants guess is a Kimberly - woodsii. Ignore Schubert choke cherry seedlings … a rampant germinator in my gardens.
