Galliformes (gamebirds and fowls) are an order of ground dwelling birds comprising megapodes, chachalacas, guans, curassows, turkeys, grouses, new world quails, pheasants, partridges and guineafowls, representing more than 290 Galleoanserae species. Their stocky bodies exhibit colorful, often sexually dimorphic plumage. In most species, juveniles display typical striped color patterns with alternating black-brown and yellow longitudinal stripes along the dorsal feather tract.
Japanese quails (Coturnix japonica)
Japanese quails have traditionally been used by developmental biologists to study the embryonic origin of several cell types (i.e., fate mapping through quail-chick grafting). Molecular tools are available thanks to its close relationship with the chicken (Gallus gallus), and today, this species is raising again as a major model organism, with the ongoing sequencing of its genome and transgenic individuals being produced.
