متن کاملGenetics, Chromatin Diminution, and Sex Chromosome Evolution in the Parasitic Nematode Genus Strongyloides
BACKGROUND When chromatin diminution occurs during a cell division a portion of the chromatin is eliminated, resulting in daughter cells with a smaller amount of genetic material. In the parasitic roundworms Ascaris and Parascaris, chromatin diminution creates a genetic difference between the soma and the germline. However, the function of chromatin diminution remains a mystery, because the vas...
متن کاملSex ratios and sex-biased infection behaviour in the entomopathogenic nematode genus Steinernema.
In experimentally infected insects, the sex ratio of first generation nematodes of five species of Steinernema was female-biased (male proportion 0.35-0.47). There was a similar female bias when the worms developed in vitro (0.37-0.44), indicating that the bias in these species is not due to a lower rate of infection by male infective juveniles (IJs). Experimental conditions influenced the prop...
