breeding dilute to dilute

Ino (Lutino and Albino) is an allele of Texas Clearbody, both being recessive mutations away from Normal, with Texas Clearbody dominant to Ino. Most who have dilute won’t know it until they have a yellow pop up since they cannot recognize a silver bar (dilute blue bar). In a bird which has two Dilute alleles (the homozygote) the number of melanin granules is greatly reduced, to around 5% of the normal amount. This is not necessarily the judges’ fault as light variables can impact in this area, and the two can be very difficult to distinguish unless one breeds them and is very familiar with them. Other sets of modifiers affect all of the varieties, apart from the Greywing-Clearwing-Dilute (Black Eyed Self) series as described above. A Normal (Light Green for example) has black wing markings and full intensity body colour (full melanin pigment if you like). Heterozygous – having two alternative genetic variants (alleles) at a given gene, Genotype– alleles carried which determine phenotype, subject to dominance or recessivity, BCSA Administration – A Historical Record, State Selection Show / Logan Shield Format 2017. Carrier dogs (D/d) do not display a dilute color and are not at risk for Alopecia, but when bred with another dog that also is a carrier (D/d), there is a 25% chance of having pups with diluted coat color that may also be susceptible to alopecia in some breeds. The term 'dilute' refers to the weakening of the colours of a cat's coat as if watered down. Similarly, green, blue, “English” yellowfaced blue and “Australian” yellowfaced blue are four alleles of a “colour” gene. The Dilute colouration in its original native form is part of the mixture of birds cobbled together as suffused yellows/whites (see page 39 of The Standard). Reliable genetic testing is important for determining breeding practices. These mutations include Danish Recessive Pied, Dominant Pied, Fallow, Opaline and Cinnamonwing.

The Dilute mutation is recessive to its wild-type allele, so a bird possessing a single Dilute allele (the heterozygote) is identical in appearance to the wild-type Light Green. Weimaraners are unique in that the dilute gene is fixed in the breed, meaning all Weimaraners are homozygous (have 2 copies) for the recessive dilute gene (dd). The “Dilute” breeders frequently refute that there is actually any such condition as Colour Dilution Alopecia, claiming it is an outdated and discredited notion, and that dogs of standard colors are equally affected by alopecia (which is false). These sheep fail to thrive and have a reduced life expectancy. In its somewhat more marked form there has been an era and unfortunately there still is in some places a habit of exhibiting these as Greywings, where the wing markings on the Dilute are heavier than usual, due to modifiers affecting that trait. In fact, breeding dilute to dilute is the best way to eliminate CDA in lines, and breeds that come only in dilute … The “Dilute” breeders frequently refute that there is actually any such condition as Colour Dilution Alopecia, claiming it is an outdated and discredited notion, and that dogs of standard colors are equally affected by alopecia (which is false). Greywing – recessive to Normal, co-dominant with Clearwing, dominant to Dilute When a budgie has two of the recessive Dilute alleles it shows the traits of Dilute with washed out markings and colour all over. As an owner and breeder of cream dilutes, and lover of all the dilute equine colours, I built the website to help others understand not only the basic colour genetics behind the various dilutions but also as a reference to assist with showing, feeding and caring for these special horses and ponies. When collected, both were emaciated, covered in faeces and had severe alopecia (baldness) patches. As you can see there are only five discrete phenotypic possibilities (ignoring the continuum comprising the suffused’s colouration and the continuum of wing markings as sometimes evident in Clearwing classes) but many more possible genetic combinations (or genotypes). These dogs can pass on either the full-colored or dilute allele to any offspring. When breeders use health testing to identify risk factors in potential breeding dogs, it can significantly decrease the likelihood of many conditions appearing during your dog's lifetime. This is the last combination possible in breeding dense/dilute. Double Dilute~ The double dilute (or homozygous white) results from merle to merle breeding. When pairing a greywing (or clearwing) to a dilute all the chicks will be greywings (or clearwings) split for dilutes. These are discouraged by judging each variety to The Standard that is designed to keep the phenotypes discrete. That would seem unlikely since such a gradual transformation has not been documented. The resulting phenotypes are sometimes referred to as multiple allelomorphs, indicating that there are visible and discrete variations of different mutations of the same gene.
