  • In situ hybridization data are shown for OR probes matching six M. mulatta OR genes.

  • aNumber of genes predicted to hybridize to each probe given sequence relationships.

  • bM. mulatta: Animals 6, 9, 10, 11, and 13; M. nemestrina: Animals 8 and 12.

  • cDensity of hybridized neurons in OE after overcounting correction and given as labeled cells/mm2 OE surface area, Avg ± SEM. Total density assuming 51% OCAM+ (see Materials and Methods). OR/animal combinations with <20 cells are not included. Fraction of OSNs is adjusted for predicted number of genes that should hybridize to each probe and thus indicates the fraction of OSNs per gene recognized by the probe. The estimated total OSN cell density is 18,590 cells/mm2 (see Materials and Methods).
