R-locus eye color factors in Mormoniella.
I N the chalcidoid wasp Mormoniella vitripennis (Walker) there has been formed by mutation a series of multiple allelic genes, each differing from wild type in one or more factors. The term “factor” is here used in an inclusive sense to denote anything which has an effect on development or which can in any other way be detected. The genes in this “R’ series are pleiotropic, unifactorial, bifact...
متن کاملMutants and Linkage in Mormoniella.
HE research of various workers has resulted in the accumulation of a large T number of mutant stocks of Mormoniella vitripennis (WALKER). Some of these mutants have been described by WHITING (1951); more recently, many others have arisen spontaneously or as the result of radiation studies conducted by KAYHART (1956) and SAUL (1955). Many of the mutants are a t the complex locus which WHITING (1...

متن کاملThe Role of Human Capital and R&D in Total Factor Productivity in the Mining Sector
Promoting Total Factor Productivity (TFP) is one of the methods to improve the competitiveness in the mining sector. Even so, it is of great importance to find a practical solution for productivity improvement. In this study, value added was measured by an innovative method based on the Divisia quantity index for seven mineral activities for the period 1994-2016. The results of calculating TFP ...
متن کاملR factor transmission in vivo.
Experimental infections were induced in weanling pigs orally both with nalidixic acid (NA)-sensitive and -resistant strains of Salmonella choleraesuis var. kunzendorf, designated RC221 and RC221NA, respectively. Prior to the time of infection, cultures of normal bacterial flora were isolated from swine fecal matter and screened for the presence of R factors. A majority of these bacterial isolat...
