Joao the below quotation is not only for you but for the other
specialist here in genetics:
you can read black or white in a scientic article that 'Gallus gallus
domesticus (chicken: CH)' is a species:
"Because the sequences of NADH dehydrogenase subunit 2 and cytochrome
b genes had been reported in five species had been reported in five
species [Phasianus colchicus (ring-neck pheasant: RP), Gallus gallus
domesticus (chicken: CH), Perdix perdix (grey partridge: GP),
Bambusicola thoracia (Chinese bamboo partridge: CP), and Aythya
americana (redhead: RH)],.."
" Complete sequence of the Japanese quail (Coturnix japonica)
mitochondrial genome and its genetic relationship with related
species.

Abstract:
The Japanese quail (Coturnix japonica; JQ) is one of the domesticated
fowl species of Japan. To provide DNA sequence information for
examination of its phylogenetic position in the order Galliformes,
the complete sequence of the JQ mitochondria was determined. Sequence
analysis revealed that the JQ mitochondrial genome is a circular DNA
of 16 697 basepairs (bp), which is smaller than the chicken
mitochondrial DNA of 16 775 bp, but the genomic structure of JQ
mitochondria was the same as that of the chicken. The sequence
homologies of all mitochondrial genes including those for 12S and 16S
ribosomal RNA (rRNA), between Japanese quail and chicken ranged from
78.0 to 89.9%. Because the sequences of NADH dehydrogenase subunit 2
and cytochrome b genes had been reported in five species [Phasianus
colchicus (ring-neck pheasant: RP), Gallus gallus domesticus
(chicken: CH), Perdix perdix (grey partridge: GP), Bambusicola
thoracia (Chinese bamboo partridge: CP), and Aythya americana
(redhead: RH)], the concatenated nucleotide sequences (2184 bp) and
amino acid sequences of these two genes were used in a phylogenetic
analysis of JQ against these five species using a maximum likelihood
(ML) method. Using the first and second bases of the codons, and the
third base of the codons indicated a phylogenic tree of [RH, (RP,
GP), (JQ, (CH, CP))]. A phylogenic tree of [RH, JQ, (RP, GP), (CH,
CP)] was determined using amino acid sequences. Because the local
bootstrap values for the JQ branch in these trees are not high,
additional sequence is necessary for construction of a reliable tree.
