How yellow?

A number of trees and shrubs that are commercially available have
"golden" cultivars, examples being Catalpa bignoniodea 'Aurea',
Sambucus racemosa 'Sutherlands Gold', and Ulmus parvifolia 'Aurea',
to name but a few.
We know that loss of chlorophyll producing tissue comes at a price to
the plant, e.g. decreased vigor, but how much is too much?
Here is a photo of a seedling of California Horsechestnut, Aesculus
californica, in a pot with normal seedlings. I'm fairly sure this is
a genetic variation rather than a nutritional deficiency, since the
other seedlings are of normal coloration. At this early stage, the
seedlings may still be drawing on nutrition from the seed endosperm,
but what about the future. Does this seedling have a chance? (I
suppose the answer will be that I'll have to wait and see)
