From: Sexual differentiation of the zebra finch song system: potential roles for sex chromosome genes
Darkfield images from in situ hybridization depicting sexually dimorphic mRNA expression for CK310795(Methyl-crotonyl carboxylase CoA) in the zebra finch song system at day 25 post-hatching. Arrows delineate borders of song regions. In lMAN (lateral magnocellular nucleus of the anterior nidopallium), males (A) show higher levels of mRNA expression (i.e. higher densities of silver grains) than do females (B). Expression was also increased in males (C) compared to females (D) in the portion of the medial striatum that contains area X in males. Scale bar = 200 μm.
