Figure 1From: A major QTL controls susceptibility to spinal curvature in the curveback guppyThe curveback phenotype. The curveback phenotype is defined as a curve that occurs primarily in the sagittal plane of the fish as an anterior lordosis (ventrally directed curve) and posterior kyphosis (dorsally directed curve) (A). Some fish also exhibit deviation of the spine on the coronal plane (B). C shows a non-curved fish. All photos are of adult female fish. Scale is in mm.Back to article page
