Whatâs the difference between grizzle and splash? And do you know what would happen if you bred a grizzle hen to a splash cock? Thank you!
Grizzle is a dominant pigment mutation that blocks pigment formation.
A lot of the birds referred to as Splash, are, in fact, heterozygous grizzles, or the Tiger allele of Grizzle.
True Splashes are a lightly marked variation of Pied. There are a LOT of different genetic variations of Pied in pigeons, most of which are recessive, but some appear to be partial dominant.
And his son, Pitch are Heterozygous Grizzle.
Pitch is Spread, which drastically diminishes the effect of Grizzle.
Heâs molting in this photo, and the pattern you can see at the base of his closest flight has the tell-tale grizzle flecking.
Many of his feathers look that way at the base, but being covered over by other feathers makes him look almost all black.
Rotkopf is Recessive Red, which acts like, and is epistatic to spread, Meaning that a recessive red bird will look Spread, whether it actually is or not.
Astrid is genetically Spread, so he could have gotten it from her with out Rotkopf needing to be.
Astridâs Shield pattern is an expression of Pibaldism, which Rotcopf does not carry.
As evidenced by his other son, Cheeks, who is not pied either.
Cheeks is also heterozygous grizzle.
As you can see in this photo of a much younger Cheeks, that grizzling is damn near full body.
This is what Grizzle looks like with out the interference of Spread or Recessive Red
Pugsly is a good example of Homozygous Grizzle and Spread:
Look how much ticking he started out with!
Here he is a month older. You can already see new, darker feathers coming in on his wing shields.
Half a month older yet, and nearly all his big boy feathers are almost entirely black.
Mostly grown, and most of his adult feathers are deep, glossy pitch black.
And here he is fully grown.
His adult feathers grew progressively less and less white, until only the most stubborn white ticks remain.
Birds who are not spread develop in the opposite direction.
Hoya is a fantastic example of a non-spread Homozygous Grizzle.
He most likely started out looking more like Cheeks.
With out the Spread gene insisting MORE COLOR!!! louder than the grizzle geneâs âHey! Letâs add more white ticking!â with every molt, you get a bird that loses more color as it grows, until only its neck, tail, and the densest color on the wings remain.
This is not the only form of Grizzle!
This German Beauty Homer, mislabled as Splash, is actually a Grizzle varient called Tiger, which turns entire feathers white instead ticking a colored feather.
Being an allele of the same gene, it inherits and develops in the same way.
This Hungarian Giant House Pigeon, mislabeled a Black Splash, is actually a really striking combination of both Grizzle variants!
True Splash is a specific pattern of Pied:
Splash tends to be defined by small, scattered, uneven white patches on an otherwise colored bird.
They are most common on the face, and can range anywhere from an overmarked prototype bald head like this bird above
To some white flights and a freckled face, like this Homer cock.
Cara could be considered a Splash.
These four birds are results of the Bald Head pied patternÂ
Blended with non pied parents:
And Money Penny, respectively.
And this ties back to the fascinating genetic variabilty of pied patterns!
You recall Rotkopf (Grizzled, not pied) and Astrid (pied, not grizzled)s children are Grizzled and carry pied, but are not pied: The typical recessive inheritance of pied.
Ferdi and Bobbiâs Bald head pattern of pied inherits like a partial dominant.
You could argue that Penny and Sun Tsu carry it, except that that pattern has not been bred into either the Show Type Racing Homer OR the Chinese Owl.
Itâs typically a trait of rollers and tumblers, with the notable exception of the Old Dutch Capuchine and Jacobin, because it enhances the aesthetic of their huge, maned crests.
There are pied homers and Chinese owls, but they are usually in the form or white flights, patches on the wing shield, and freckles about the head.
And when two pied varients are mated together, you usually get a blend of those patterns:
Schatzi, whose pied expression is bleeding into her Shield on one side
Who is, charmingly enough, uneven on exactly the same side as his Mother.
You see the same uneven pattern in his little sister.
Less marked on the same side.
Out of Astrid, who is perfectly even in the shield, Ferdi has thrown
And her little sister, who are each, in their own right, perfect blends ofÂ
But in the case of the Splash children out of Bald Head x Full Colored parents, you just see a half-expressed Bald Head pattern:
Cara, in whom you see the half expressed Bald Head patternÂ
in exactly the same way you see her Father
Who all display a variation of half expressed Bald Head.
So, a Grizzle mated to a pied would DEFINITELY throw Grizzled children, but whether or not they were also pied would depend on the variant of pibald.
Mostly, that pairing would throw grizzled children who carry, but donât express pied. (Like Pitch and Cheeks)
But you could also get heterogygous grizzled children with partially expressed pied traits.
A blend of both traits fully expressed would most likely resemble this German Beauty Homer over all:
(Though you can tell heâs most likely a blend of the two grizzles by his lack of white flights.)
