chimera of watermelon

Chimera-also known as a somatic mutation, affected leaves often lack pigment in mottled patterns. Since the mutation occurs in portions of the plant after germination, the patterns may affect only a portion of the plant. This is not an infectious problem and rarely causes any economic loss. Somatic mutations also occur in other crops.
