The other three members of the genus — [[Sri Lanka junglefowl]] (''G. lafayetii''), [[grey junglefowl]] (''G. sonneratii''), and [[green junglefowl]] (''G. varius'') — do not usually produce fertile [[Hybrid (biology)|hybrids]] with the red junglefowl. However, supporting the hypothesis of a hybrid origin, research published in 2008 found that the gene responsible for the yellow skin of the domestic chicken most likely originated in the closely related grey junglefowl and not from the red junglefowl.[ Similarly, a 2020 study that analysed the whole genomes of Sri Lanka junglefowl, grey junglefowl, and green junglefowl found strong [[Introgression|introgressive]] hybridisation events in different populations of indigenous village chickens.][ The study also shows that 71–79% of red junglefowl DNA is shared with the domestic chicken.][ A culturally significant hybrid between the red junglefowl and the green junglefowl in Indonesia is known as the ''[[bekisar]]''.] |
