Skull asymmetry in sheep is dominated by right side

Random deviations from the perfect symmetry of normally bilaterally symmetrical characters for an individual with a given genotype occur during individual development due to the influence of multiple environmental factors. Directional asymmetry (DA) indicates that one side is consistently and signifc...
