knirps and cubitus interruptus loci interaction in wing veins pattern formation in Drosophila melanogaster (morphology analysis)
Abstract
We studied the expressivity of radius incomletus and cubitus interruptus traits of Drosophila melanogaster imagoes, depending on the individual’s genotype, sex, and analyzed wing. It has been established that the presence of kniri mutation leads to the change of cubitus interruptus trait expressivity (partial suppression of mutant phenotype at the background of general venation pattern changings). On the contrary the presence of ci1 mutation in the genotype does not affect the radius incompletus trait expressivity. Males demonstrate more pronounced expressivity of both traits than females. No bilateral asymmetry in the expressivity of corresponding mutant features has been detected. Standing on the results obtained we suppose that knirps and cubitus interruptus loci do interact in wing veins pattern formation, and knirps is the regulatory factor for cubitus interruptus expression.
