How many chromosomes are in an ant?
The number of chromosomes per individual varies from one to over 70 among the species in the genus. The genome of M. pilosula is contained on a single pair of chromosomes (males have just one chromosome, as they are haploid ). This is the lowest number possible for any animal, and workers of this species are homologous. Like M. pilosula, M. croslandi also contains a single chromosome. While these ants only have a single chromosome, M. pyriformis contains 41 chromosomes, while M. brevinoda contains 42. The chromosome count for M. piliventris and M. fulvipes is two and 12, respectively. The genus Myrmecia retains many traits that are considered basal for all ants (i.e. workers foraging alone and relying on visual cues).
