Abstract. The chromosome number for the red and black imported fire ants, Solenopsis invicta Buren and S. richteri Forel, was determined to be n = 16. A special case of diploidy in S.
What is the haploid number for fire ants?
S. invicta and S. richteri share a haploid number of 16 with 2 native fire ant species, aurea and geminata, whereas 3 small Solenopsis species have n = 11 (Crozier 1970, 1975).
How many chromosomes does a female ant have?
2 for females, males are haploid and thus have 1; smallest number possible. Other ant species have more chromosomes. The 2n=6 chromosome number is conserved in the entire family Culicidae, except in Chagasia bathana, which has 2n=8. 2n = 6 for females and 7 for males.
Are all fire ants female?
Fire ants were the social insect of choice because they have only one queen per colony, and because their colonies tend to “specialize” in producing mostly male or mostly female offspring.
What gender are fire ants?
In a bizarre war of the sexes, little fire ants have evolved a novel way to fight for their gender’s genes, according to new research. The sperm of the male ant appears to be able to destroy the female DNA within a fertilized egg, giving birth to a male that is a clone of its father.
How many homologous pairs does a fire ant have?
We find that fire ants have 24 OBPs, 10 of which are in the social chromosome. Two of the social chromosome OBPs are exclusive to alternate social chromosome variants, and four OBPs in addition to Gp‐9 have differences in amino acid sequence between the variants.
How many chromosomes do ants have?
Ants belong to the taxonomic insect order Hymenoptera, which also contains bees, wasps, hornets and sawflies. All hymenopteran species so far studied that have a diploid chromosome count above 52 (i.e., above 26 pairs) are ants. N.
Which animal has highest number of chromosomes?
The mitotic and meiotic chromosomes of the semiaquatic rodent Ichthyomys pittieri (Rodentia, Cricetinae) from Venezuela were analyzed by means of conventional staining and several banding techniques. The diploid chromosome number of this rare species is 2n = 92, which is the highest value known for mammals.
How many fire ant bites will kill you?
According to deShazo, the medical complications of fire ant stings can range from mild irritation at the sting site to death from a generalized allergic reaction, depending on the number of stings and the physical condition of the victim. Fire ant stings at the ant mounds or outdoors have caused at least 80 deaths.
