Figure 2.

Colony number 27 raised by a queen collected in March 1979 from Smith River, California (see Figure 11 and Table 1 in Owen and Plowright, 1980). The genotype of the black queen is inferred to be r/r and she was mated to a red (R) male, thus all the workers in the colony are red and heterozygous. High quality figures are available online.
