Yellow crazy ants, an infamous invasive species predominantly found throughout Southeast Asia and Oceania, have a remarkable reproductive system.<\/span><\/p>\n Researchers have discovered that male ants in this species contain two different cell lineages, an occurrence referred to as chimerism.<\/span><\/p>\n This feature has never been observed as a vital component of any other animal’s biology.<\/span><\/p>\n The presence of chimerism in these ants was identified by examining genetic markers scattered across their genomes.<\/span><\/p>\n In general, male ants develop from unfertilized eggs containing a single genome copy. However, yellow crazy ants surprisingly display males with two genome copies.<\/span><\/p>\n Further investigation revealed that each male cell consists of only one version of the ant’s genome, with some cells possessing a lineage present in queens (R chromosome) and others carrying a distinct genome (W chromosome).<\/span><\/p>\n The study demonstrated that chimerism has a significant role in determining the caste system of yellow crazy ants.<\/span><\/p>\n All eggs produced by the queen contain one copy of the R genome. If an egg is fertilized by a sperm cell carrying an R genome, the result is the development of a queen.<\/span><\/p>\n On the other hand, if the egg is fertilized with a W sperm, two potential outcomes can occur.<\/span><\/p>\n If the cell nuclei fuse, the egg develops into a diploid worker ant. If the nuclei do not fuse, the egg matures into a chimeric male, with some cells containing the R genome and others the W genome.<\/span><\/p>\n The chimeric males exhibit an irregular distribution of R and W cells throughout their bodies.\u00a0<\/span><\/p>\n While the majority of their body is composed of R cells, sperm cells are predominantly made up of the W lineage.<\/span><\/p>\n Yellow crazy ants, an infamous invasive species predominantly found throughout Southeast Asia and Oceania, have a remarkable reproductive system.<\/p>\n <\/span>\r\n\r\n The reason behind the evolution of this unique reproductive mechanism in yellow crazy ants remains a mystery.<\/span><\/p>\n One hypothesis is that by not fusing with the egg cell, the sperm might boost its reproductive potential.<\/span><\/p>\n This could be the result of an interaction between two conflicting genomes that occasionally cooperate.<\/span><\/p>\n These distinct lineages may have evolved separately in two different ant populations that eventually mixed, or they could have originated from similar genes that diverged over time.<\/span><\/p>\n This atypical reproductive method could offer certain benefits to the ant populations, contributing to the yellow crazy ant’s infamy as one of the most detrimental invasive species worldwide.<\/span><\/p>\n The ants successfully avoid inbreeding, as the fusion of R and W nuclei only leads to the development of sterile workers, preventing the genomes from mixing and being passed on to future generations.<\/span><\/p>\n Although chimeras have been identified in other creatures, including humans, it is typically an unintended event.<\/span><\/p>\n Yellow crazy ants are the first known species in which chimerism determines an individual’s sex.\u00a0<\/span><\/p>\n Nevertheless, the reproductive systems of the majority of the estimated 20,000 ant species have not been explored, raising questions about the prevalence of similar systems in other ant lineages.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":18,"featured_media":155357,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[411],"tags":[],"class_list":["post-155354","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-special-interest"],"acf":[],"_links":{"self":[{"href":"https:\/\/culture.org\/wp-json\/wp\/v2\/posts\/155354"}],"collection":[{"href":"https:\/\/culture.org\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/culture.org\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/culture.org\/wp-json\/wp\/v2\/users\/18"}],"replies":[{"embeddable":true,"href":"https:\/\/culture.org\/wp-json\/wp\/v2\/comments?post=155354"}],"version-history":[{"count":0,"href":"https:\/\/culture.org\/wp-json\/wp\/v2\/posts\/155354\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/culture.org\/wp-json\/wp\/v2\/media\/155357"}],"wp:attachment":[{"href":"https:\/\/culture.org\/wp-json\/wp\/v2\/media?parent=155354"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/culture.org\/wp-json\/wp\/v2\/categories?post=155354"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/culture.org\/wp-json\/wp\/v2\/tags?post=155354"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}Chimerism and Its Impact on Ant Caste Structure<\/strong><\/h2>\n
