Some time ago at the invitation of The Splendid Bourke Bird Blog, I did a profile with genetic information on bourke grasskeets. The article can be found here at: http://thesplendidbourkebirdblog.blogspot.com/p/bourke-genetics.html.
More pictures of the various mutations and combinations of mutations are available at: http://grassparrots.free.fr/bourkes'p/bourkpmut.htm.

A Profile of Scarlet Chested Grasskeets aka Scarlet Chested Parakeet - Neophema splendida
Scarlet chested grasskeet aka splendid grasskeet is a popular species of parakeet from Australia. They are quiet birds in general but males will sing a quiet song to entice his mate. They are peaceful and mixes well with non-aggressive finches and other grasskeets in general, but would avoid mixing with aggressive species or larger hookbills. They enjoy larger flights - minimum 30"x30" per pair, and do well with a standard parakeet diet of seed mix, greens, and eggfood. Given the right conditions, they readily breed. Health wise, they are considered a bit more delicate than other grasskeets like turquoisines and bourkes - warmer and dryer conditions are appreciated. I started keeping scarlets in 2008 after seeing pictures of them online. After doing some intense research, I just knew I had to start keeping them. Although the normal scarlet is probably one of the most beautiful birds in aviculture, another reason for their popularity is the availability of many mutations. Now, I will try to give a brief description of the more commonly available mutations although a lot of the mutations and better examples of the mutations are much more readily available in Europe than the USA.
NORMAL:
 |
| mature adult normal male |
 |
| young normal hen |
LUTINO: like most lutino mutations, it is sex-linked recessive

CINNAMON: sex-linked recessive

PALLID: sex-linked recessive

BLUE: autosomal recessive. This is probably the most complicated and confusing since there are several blue mutations that are incompletely dominant to each other. Overall, there is seagreen aka aqua, turquoise, and white front blue. Sometimes aqua and turquoise are referred to as par-blue. I've read that white front blue is a combination of seagreen and turquoise. With a lot of interbreeding of the different blue mutations, sometimes it can be a challenge to know exactly what a bird is.

GREY: autosomal dominant. The grey can be combined with any normal or mutation scarlets.

VIOLET: autosomal dominant. Can be combined with any normal or mutation scarlet, but since it affects the blue color, will show up best in the blue series. Double factor will be a more intense effect than single factor.

PIED: autosomal dominant. Can apply to any normal or mutation scarlet.

RED FRONT: modification that can be improved with selective breeding
