Figure 1 Models for how differences in sex-specific reproductive behaviors are specified. (A) Illustrations of female (left) and male (right) flies are shown. (B–E) Yellow and pink curly lines represent fru+ neurons in female (left) and male (right) flies. (B) Males have a set of neurons that are absent in females. (C) Males and females have homologously positioned neurons that differ in physiology and/or fine-scale connectivity. (D) Males and females have homologously positioned neurons that differ in arborization and connectivity. (E) Males and females share some homologously positioned neurons, but differ in neuron number.
