Originally, S. invicta was believed to be a red form of the black species S. saevissima richteri Forel. In 1972, Buren described the black imported fire ant to be a separate and distinct species, S. richteri Forel, and the RIFA was identified as S. invicta Buren (Hedges 1997).
Homologous recombination is a type of genetic recombination in which nucleotide (molecules which are joined make the structural units of RNA and DNA) sequences are exchanged between two similar or identical molecules of DNA.
Â· just now. Report Abuse. Genetic recombination is the process by which a strand of genetic material (usually DNA; but can also be RNA) is broken and then joined to a different DNA molecule. In eukaryotes recombination commonly occurs during meiosis as chromosomal crossover between paired chromosomes. This process leads to offspring having different combinations of genes from their parents and can produce new chimeric alleles.
