Genetic mechanisms of sex determination are unexpectedly diverse and change rapidly during evolution. We review the role of genetic conflict as the driving force behind this diversity and turnover. Genetic conflict occurs when different components of a genetic system are subject to selection in opposite directions. Conflict may occur between genomes (including paternal-maternal and parentalzygo...
Five newly identified sex-biased transcripts in Drosophila are full of surprises: although they are found in fly heads, and manipulating two of them affects mating behaviors, their genes are expressed sex-specifically in non-neural tissues. The way these genes are regulated suggests new complexities in the sex determination pathway.
only when the compound capable of tautomerization is in the liquid phase, or in solution. And that is just the case with the free radicals under consideration. 6. The two radicals, a-naphthyl-diphenylmethyl and a-naphthylxanthyl, were found to give a molecular weight less than that calculated for the monomolecular phase. Schlenk and Renning's" results show that a-naphthyl-biphenyl-phenylmethyl ...
