The Indian Blue Pied peafowl carry an extra colour from the Indian Blue. This being white. Pied meaning a white marking.
The Pied pattern can occur in almost all varieties of peafowl. It is an incomplete dominant gene, and is an allele of the white gene.
Type of mutation:
Indian Blue Pied is a pattern mutation, and is often represented in genetic crosses as TP.
Males appear like regular India Blues except that they are speckled and splotched with white. Exceptional birds will have white on their back and in their train.
Hens are also normally colored except for the white splotches.
Do they breed true?:
No. A Indian Blue Pied (TP) times pied (TP) cross will result in 25% of offspring white (TT), 50% pied (TP), and 25% dark pied (PP). Dark pied offspring appear very similar to the India Blue, but white can be found on their wing primaries, and they carry the pied gene. If they are bred to whites, 100% of the offspring will be pied.
and develop much like the India Blue, except for the shoulders, which start out white and do not completely change to black until its second year.
