Oligonucleotide primers were designed to discriminate between the Gp-9 B and Gp-9 b alleles found in monogyne and polygyne colonies of fire ant, Solenopsis invicta Buren. Primers specific for the Gp-9 B allele produced a 517 bp amplicon and primers specific for Gp-9 b allele produced a 423 bp amplicon. When both sets of primers were multiplexed, homozygous monogyne ants produced a single 517 bp amplicon (specific for Gp-9 B ), whereas heterozygous polygyne ants produced one 517 bp amplicon and one 423 bp amplicon (specific for Gp-9 B and Gp-9 b , respectively) which allowed the Gp-9 alleles to be discerned in a single reaction. This method was tested on ants from 20 monogyne colonies and 20 polygyne colonies and was 100% accurate in discriminating the two forms.
