陨石色卡迪根的搭配限制

安妮柯基

上图是一只白色失格的卡迪根威尔士柯基犬，之前讲过卡迪根毛色搭配限制，今天凌晨和美国AKC卡迪根俱乐部的犬舍聊天时候提到陨石色的搭配繁殖问题，这是一个非常苛刻的限制。

之前我们提到过卡迪根的毛色搭配问题，说到渐变色除本色外只能和纯色搭配，但是我们忽略了陨石色。陨石色是不能够和陨石色搭配的。在今天的内容中我们将对这一原则重新更正并讲解原因。


陨石色卡迪根（MERLE COAT）的搭配限制很严格。

首先：两个陨石色的卡迪根搭配是不被允许的！因为 陨石色的互相搭配有25%的几率出现纯合子（MM）这样出生的宝宝(DOUBLE MERLE)除了很可能毛色会几乎全白外（白色失格），还有很大的可能出现听觉，视觉的缺陷（比如一只耳朵听力全失、双目失明等）。所以这样的繁殖是不安全繁殖。



然后，陨石色的卡迪根可以和哪种搭配呢？答案是黑白色的卡迪根 ，黄白黑三色卡迪根，黑白色带虎斑脸卡迪根。


我们再说一下为什么两只陨石搭配除了白色失格以外会出现一些缺陷？

相关的文献我暂时没有找到，但是网络上有一种说法是控制白色毛发的基因和控制蓝色眼睛的基因是同属一组基因。眼睛变蓝就是基因白化的表现。所以不管是彭布罗克还是卡迪根，只有陨石色才允许出现蓝色眼睛，除此以外全部视为失格。失明是基因白化的极端表现。所以蓝色眼睛的威尔士柯基犬们（除陨石色卡迪根威尔士柯基外）是不允许用于繁殖的。

所以如果您饲养了一只蓝色眼睛的柯基犬（并非陨石色卡迪根），那么作为宠物犬没有任何问题，请不要用它来进行繁殖，多谢！

然后大家都知道我们安妮家在出售一窝卡迪根幼犬，很多朋友私下里想跟我们预定下一胎的陨石色母犬，然后打算找父亲（陨石色）回血繁殖，但是今天这样讲解以后，我们是不会允许陨石色母犬来借配我们家陨石色种公的。所以预定陨石色母犬的朋友，需要考虑的是这窝仅有两只的黑白色带虎斑脸的公犬（陨石色不能和虎斑色搭配）。
诶。好吧，也算个小小的广告。
安妮家的卡迪根种群在有计划的逐渐扩大规模。也希望喜欢这一犬种的朋友们和我们一起繁荣这个市场。

1. Blue merle to tricolour always produces blue and tri in fairly equal numbers, i.e. if a bitch produces 30 puppies over a number of litters, they will roughly divide into 15 blues and 15 tris. There may be one or two puppies either side of this number, but not too far from equal numbers. (A)



2. Blue merle to brindle point tri will always weaken the red pointed tris, but will produce blues with less tan on points. Again they will divide almost equally if the bitch is mated to the same dog on a number of occasions. You have to take the average out of 30 whelps every time.



3.    Blue merle to black and white holds a certain fascination for me, producing variations according to skin colour of the black/white. For instance as long as the black/white has a blue skin (not pink or white skin colour) it does not matter if the black/white has no blue breeding behind it at all it will produce only blue and black/white puppies. However, if the black/white has a blue or tri parent you can get blue, black/white and tricolours both brindle pointed and red pointed.

By using black/white you can diminish the red pointing on blues which does have a tendency to become too much when using red pointed tricolours for too many generations. Also black/whites do tend to bring the clear silver blue to the fore and "clean up" the blue colouring. All too often we see the "muddy blue" coat where a lot of red in the undercoat has been influenced by the brindle behind a tricolour. Using black/white will usually clear this problem up in one generation although it can take up to two generations in some cases.

When doing the blue to black/white mating, you should always try to get back to tricolour for the next generation mate if possible, otherwise you will find no tricolours around in a few years, as has almost happened in England. (B)



4.    Blue merle to blue merle. This mating has to be thought about very carefully beforehand. If the two blues have a lot of black on the body you can be lucky and not produce whites. If either parent has little black on the body you will almost certainly get one or two whites in the litter. White puppies you will find always to be deaf and possibly blind as well so they should be put down at birth to save them suffering later in life. When doing this mating you will get blues and tris only as well as the possibility of all white.



5.    Blue merle to red/white. For this mating you need to look to long term plans with space, time and money as more than often the first generation colour is not good. But by putting a puppy from this mating back to black/ white can take 2—3 generations to get the desired effect and few people these days can afford to have a kennel large enough to carry out this type of experimental breeding program. From this mating you can get blues with red undercoat, tricolours and red/whites with sometimes blue eyes. However as this mating has not to my knowledge been done in any concentration I can give no exact proportions. (C)



6.    Blue merle to brindle. This mating should never be done as both are recessive genes and will work against each other producing off colour blue merles. This can cause havoc for many generations of breeding plans and can also cause liver pigment which can be dangerous with organ defects. (D)
