I like to see birds with white flights. I think they look really nice when they spin. JMO wondering how white flights fits in color genetics. I assume it is a color modifier? But wondering if it is sex linked, dominate, recessive, etc? Thanks for the help.

RT,
I dont know about the recessive or dominance. I get quite a few from the white flights I breed from. White flights are part of the T patten. Which can include a white tail and smaller white markings on the head. Baldies are different they have bulleye(s)and WFT. The bulleye is the easiest way to tell cuz some baldies have imperfect markings.
The white was brought in to help the frequency. I dont know if it was selectively bred for or a cross was used.
Thats about the extent of my knowledge on white flights.

The pied (piebald) gene is responsible for white flights, white tail, baldhead, beard, mask, badge, splash, and saddle markings and various combinations. It has a partial dominant effect. With autosomal type genes (non sex-linked), the parents each have two genes for each attribute. When they reproduce, they each will contribute one of their two possible genes with the egg and sperm. So the offspring similarly have two genes, one from each parent. Dominant genes dominate the outcome (phenotype - meaning outward appearance) when a pair of autosomal genes is different (heterozygous). The gene in the dissimilar pair that is dominated is called a recessive gene. For example, most pigeons carry a pair of identical genes (homozygous) for the wild type (recessive) of appearance, but those with at least one spread gene (dominant) of the pair and one wild type of gene will be appear black if a blue series pigeon, or lavender if an ash red series pigeon (blue and ash red are sex-linked genes). As an example in the case of dominant genes, if an offspring inherits one spread gene from each parent, and has both spread genes (homozygous) in that pair of genes for that trait, it will be the same phenotype as the heterozygous condition. For a recessive trait to display itself, both of the autosomal genes in the pair of genes must be of that same recessive trait (e.g., grouse leg). Codominance means that the heterozygous condition of a trait (e.g., grizzle) will appear different phenotypically than if it is in the homozygous condition. For example heterozygous grizzles appear somewhat similar to each other (within each genetic type of grizzle), however homozygous grizzles are mostly white with only little patches of color. Partial dominance means that the heterozygous condition will be almost intermediate to the homozygous condition, but with more unpredictable variability. That is why the pied gene(s) (partial dominant effect) and interactions are less well understood than other types. About one member of each of my breeding pairs carry the pied gene in some fashion, most commonly as white flights. White flights are probably pied in the heterozygous condition. Baldheads with white flights and tail, and splash marks are probably carrying the pied gene in the homozygous condition. Bulleyes are also associated with the homozygous condition, probably as the result of another gene interaction. Breeding pieds together yields variable unpredictable effects in the white patterns of the offspring, when the offspring is homozygous. If the parents are both heterozygous for pied, offspring probably have a 50% probability of being pied in a heterozygous condition, 25% probability of homozygous, and 25% probability of normal nonpied appearance. Wilmer J. Miller, a retired Iowa genetics professor I have spoken with on a couple of occasions with has done some work with regard to the pied gene in ringneck doves and pigeons. The best most reliable single source for all other areas of pigeon genetics information is regarded to be Axel Sell's book "Breeding and Inheritance in Pigeons". It contains many color pictures and is available in the Rollerpigeon.com store.

White Fights is neither dominate nor recessive, or sexlinked?
but a co-dominate trait.
So a bird that has only one white flight feather per wing is a carrier for white flights, but has other factors stopping a complete white flight phenotype? and a bird with White flight is a carrier but bred to a non-white flighted bird may never have White flighted offspring if the mate has the a more dominant color gene to cover the flights?
?

Most of my birds carries w/f...That's what i like most about them is when they roll you could see the w/f shine especailly when the sun shine at them and it makes it easier to spot them in the air...
