Statistic Morphology Difference between Sexual Dimorphism of Paramisgurnus dabryanus Sauvage
摘要
Abstract
[ Objective ] The aim was to compare the morphology difference between sexual dimorphism of Paramisgurnus dabryanus Sauvage.[ Method ] The comparison of 10 morphological characteristics between sexual dimorphism of P. dabryanus was conducted with principal component analysis and t-test methods. [ Result] The results of t-test indicated that three of 10 morphological characteristics showed extremely significant difference(P ＜ 0. 01 ) and one of 10 morphological characteristics was significantly different (P ＜ 0. 05 ). Principal component analysis revealed four principal components, the contribution rate of which was 31. 151％, 18. 844％, 12.324％ and 10. 169％, respectively. The cumulative contribution rate had reached 72. 487％. The morphological variations between sexual dimorphism were not significant, which was consistent with that of t-test. [ Conclusion ] The result in this study had provided theoretical basis for the breeding of P. dabryanus.关键词
