X chromosome inactivation (XCI) is that one of two chromosomes in mammalian females is silenced during early development of embryos. There has been a statistical measure for the degree of the skewness of XCI for qualitative traits. However, no method is available for such task at quantitative trait loci.

Tyrosine kinase inhibitors (TKIs), such as sunitinib, are used for cancer treatment, but may also affect platelet count and function with possible hemostatic consequences. Here, we investigated whether patient treatment with the TKI sunitinib affected quantitative and qualitative platelet traits as a function of the sunitinib level and the occurrence of bleeding.

Achene micromorphological evidence belonging to 32 species of Potentilla from Iran were studied using scanning electron microscopy (SEM). Multivariate analysis was used to estimate the potential contribution of the quantitative and qualitative traits to the species relationships. Based on the present results, the achene micromorphological traits exhibited considerable variations.

The present study was conducted to assess the growth performance of Casuarina clones in clonal trials located at Kunchenahally and Sindigere of Karnataka. There was a significant difference in quantitative and qualitative growth traits among the clones. CH-10 showed better growth performance at Kunchenahally, whereas CH-4 performed better at Sindigere site, respectively. Clone CH-4 exhibited better growth performance among all the clones across the two sites.

Hence the present investigation carried out for genetic variability for quantitative and qualitative traits in genotypes of tomato. The knowledge of genotypic and phenotypic coefficient of variation is being useful in designing selection criteria from variable population. In general, it was noted that the value of phenotypic coefficient of variation is higher than the genotypic Coefficient of Variation For all the traits.

The present investigation was undertaken for combining ability studies on quantitative and qualitative traits at C.H.F., CAU, Pasighat, A.P. The 28 F1 hybrids were developed by crossing 8 diverse brinjal genotypes/varieties in half diallel fashion. The variances due to GCA and SCA were significant for most of the characters indicating the importance of both additive and non-additive gene action in the inheritance of these characters.

Gene action for various quantitative and qualitative traits was explored in a half diallel involving seven elite inbred lines. Variance/Co-variance graphs revealed that the yield potential traits like (days to 50% pollen shed, days to 75% brown husk, plant height ear placement height, ear length, kernel rows per ear, kernel per row, test weight and grain yield,) displayed that the intercept of the regression line was negative showing over dominance type of gene action.
