Biology
A chimera is part of a vine comprised of 2 or more genetically different tissues. It is usually the result of a vegetative mutation. It may be expressed as leaves that are bigger, smaller or of a different shape, variation in growth habit (more upright, more compact, shorter internodes), colour (absence of chlorophyll or anthocyanin, teinturier), or flavour (e.g. Chardonnay vs. Chardonnay musqué).
