Abstract

The present investigation has been focussed on the inter-chromosomal and intra-chromosomal asymmetry data of Allium sativum and Scadoxus multiflorus of Amaryllidaceae using quali-quantitative and quantitative methods. The quail-quantitative analysis is strictly ratio based and it revealed that the karyotype of A. sativum and S. multiflorus belonged to category 1A and 3C respectively indicating only the degree of asymmetry. The coefficient of variation of chromosome length (CVCL) and the mean centromeric asymmetry (MCA) were the estimators of quantitative analysis and the data showed that the inter- and intra-chromosomal asymmetry were comparatively high in S. multiflorus than that of A. sativum. Further, the genetic distance between these two species is clearly visible in the bi-dimensional scattered plot from the derived MCA and CVCL data.
