Description |
The growth indices of the Mussels, Perna viridis and Perna indica collected from the south west coast of India were examined using statistical methods. The Principal Component Analysis (PCA) and Exploratory Factor Analysis (EFA) separated 2 morphometric gradient groups (spat and adult), indicating the different phenotypic plasticity between them. The factor scores classified P. indica as a unimodal, positively skewed leptokurtic population and P. viridis as a unimodal, negatively skewed leptokurtic population. The allometry was not static, but simple and ontogenetic since their population was continuously varying. The present study shows that factor analysis is better than principal component analysis for delineating the morphometric characteristics of living organisms
