====== Hybrid ====== A genetic hybrid carries two different [[allele]]s of the same [[gene]], where for instance one allele may code for a lighter coat colour than the other. A structural hybrid results from the fusion of [[gamete]]s that have differing structure in at least one chromosome, as a result of structural abnormalities. ---- [[Hybrid vascular neurosurgeon]]. ---- [[Hybrid operating room]]. ---- [[Hybrid treatment]].
