Figure 5 From: Initiation of male sperm-transfer behavior in Caenorhabditis elegansrequires input from the ventral nerve cord unc-18 expression in the developing male tail. Nomarski (A), fluorescence (B) and merged (C) images of unc-18::YFP expression in the developing male tail (L4). Animals are pha-1(e2123ts) young adult males transformed with the extrachromosomal array pha-1+unc-18::YFP.Back to article page
