标题: 猫猫交配问题，请大家指教。
家里的小家伙来了已经半年了！现在想帮它找个老婆！这几天在网上找了一些资料，有些说到同色系不能交配什么之类的信息。又有些人说可以！现在很纠结。所以上论坛求解一下：猫猫交配的问题！
猫猫简历：
名称：点点
色系：银斑

问题：想帮它找个银斑的MM，不知道可不可以！要是不可以的话那最好是找什么色系的MM给它做老婆呢？

银版和银版貌似不好配的，白+白基因致死，可以配黑色系啊，米色系啊神马的。

专业的等高人来解答啊

嗯，银斑和银斑肯定不能配的~配个米色的应该可以~配个标灰也可以

作者: kinny0326 时间: 2011-5-20 15:19
白+白=致死基因
丝绒+丝绒=致死基因
银斑就别配白色系
包括粉白什么的
都不能配

而且看你头像的照片
你家猫给我的感觉像丝绒银斑
安全起见你也别买丝绒系的

我对色系不了解！
现在就是想给它找个好一点的老婆，再加上我家里的女人不喜欢标灰。所以想问一下能不能直接说个安全一的色系。然后我直接去招个MM回来就行了。谢谢了。

你头像照片我看过去感觉是丝绒银斑
照片小有点看不清晰
不喜欢标灰么那你就配米色咖啡这些都可以
黑色的也可以（不过丝黑不行）

我上传个照片给你看看！到底家里的小家伙是什么色系的！

有正面的不？？？

银斑别跟粉白银斑配就可以啦。
其他看LL喜欢什么颜色了

我家的是丝绒熊人黑MM 和丝绒银斑DD 已经交配了。。交配栓都看见了。。怎么办啊。。。会不会有事啊！！高手帮忙。。要是有事我该怎么办啊！！总不能去作流产吧。。刚一个月，母猫自己一人在笼子里老是乱跳，很烦躁。。会不会出事啊！我不要小猫。保住大猫就行

如果是丝绒和丝绒基因结合就生不出来了，母猫和其他小猫可能有危险。
ls的小孙孙有25%可能性有丝丝基因。如果最后平安分娩了，也无法知道是没有丝丝还是丝丝挂掉了妈妈没事。

We hear about the lethal factor when breeding chinchillas.

Do not breed a white chinchilla to any other type of white chinchilla.
Do not breed a velvet chinchilla to any other type of velvet chinchilla.

What does it mean?

A lethal is the result of a defective gene that causes a disturbance in the development of the growing organism that then causes it to die. There are many different kinds of lethals. They occur in any species, even humans (ex. cystic fibrosis). Lethals occur in either a heterozygous (single gene) or homozygous (double gene) state. A heterozygous lethal only requires one copy of the gene to cause a problem and that problem rarely allows the organism to reach sexual maturity, so the gene cannot be passed and dies out in the first generation. It is the homozygous lethal that we have to monitor because these genes can function in a heterozygous or "carrier" state.

Which chinchillas have a known lethal factor?

Of the mutation colors associated with chinchillas, only dominant white and domianant black (velvet) chinchillas have a lethal factor associated with their genotypes or genetic makeup. These lethals only occur in the homozygous state, so there are no homozygous whites or velvets. All whites and velvets are then heterozygous for those genes. They are unaffected by the lethal because the affected genes are paired with normal genes that act as backups for those functions that the affected genes cannot perform. Keep in mind that the white and velvet lethals are two different kinds of lethals and perform separately from each other. If you breed a white chinchilla to a velvet chinchilla, there is no lethal. It is when we breed two whites or two velvets that two of the same genes may combine in the offspring and cause the lethal.

Are we even sure these lethals exist in chinchillas?

During the early development of both the white and velvet chinchilla, breeders attempted to breed animals that were homozygous for these genes. A chinchilla that is homozygous for a gene will always pass that gene to its offspring and so has a lot of value in a breeding program, but all chinchillas proved to be heterozygous by producing normal-colored offspring. It was clear that no homozygous animals were being born. Reviewing the productivity of those animals also indicated that production went down when white x white or velvet x velvet were bred. When those same animals were switched to dissimilar partners, production went up and more babies were born. It was then suggested that the white and velvet genes were linked to a lethal factor.

So what happens when a lethal is present?

Most lethals are known to cause death in the early embryonic (or pre-embryonic) stage, resulting in a lack of production because fewer babies are born. The embryos are reabsorbed by the mother. Scientific evidence in both mice and rats supports this theory. No studies have been done on chinchillas (none that the author has been able to find and verify), but this is what breeders assume happens in the case with both the white and velvet chinchillas.

Is it dangerous to breed lethals?

In the author’s opinion, the information about the dangers of breeding lethals as found in chinchilla species is inconclusive (whereas the breeding of lethals in other species is better documented and no argument can be made for the breeding of). Some speculate that the process of reabsorbing dead embryos may increase the risk of infection to the mother depending upon the stage of development during which the embryo actually dies. Others feel it poses no threat. It is also suggested that breeding white x white leads to more complications than velvet x velvet (even suggesting that velvet x velvet is acceptable). It is difficult to know if reports of post-birth complications are actually associated with the lethal or other genetic factors.

Keep in mind that not all organisms affected by a lethal will die in the womb. An example of this is the Overo Lethal White syndrome in horses. A foal that is homozygous for the OLW gene will die within a few days after birth because its intestinal system has not properly formed and it cannot function properly when it eats. Some lethals may allow for viable organisms part of the time. These are referred to as semi-lethal. The merle gene, commonly found in species like dogs and rats, causes a splotchy, spotted coat in the heterozygous state and a predominantly white coat in the homozygous state. The double-merle or homo-merle may also be affected by health problems associated with organ development (eyes, ears, digestive, etc.).

As such, or until more research is done, the breeding of lethals should not be attempted by pet breeders. If you still wish to breed lethals, the first thing you have to ask yourself is why you need to breed them in the first place (since the author cannot think of a very good reason why a pet breeder would need to do so). Some people feel that breeding lethals will result in more mutant offspring, but this is a misconception on their part.

上文的主要观点是，白白，丝丝结合是致死基因，这两对基因使得胚胎不能发育完全，宝宝还没发育就挂在子宫里了，然后被子宫吸收了。挂了之后对妈妈有影响么？一种说法是有，会感染子宫。一种说法是没事。两个说法都没有盖棺定论。BUT，别尝试这种致死基因，因为没必要，根本繁殖不出来。

只有白和白丝绒和丝绒还有近亲和近亲不可以！我有个朋友同是丝绒+丝绒生出来的bb有一边是没有眼睛的！好可怕~

那就是说丝绒和丝绒的父母怀上了带两个丝绒基因的宝宝，该宝宝被母体吸收了，但是在子宫里祸害了一位兄弟姐妹？

真恐怖~那标灰的话没有禁忌吧？不会不能陪标灰吧

作者: canghai129 时间: 2011-5-26 00:22
标灰没事，什么媳妇都能娶

作者: 〃喜欢メ微笑 时间: 2011-5-26 12:10
我觉得还是配个黑色猫或者标灰吧。基因还是比较稳定的。

作者: lzlost 时间: 2011-5-26 19:40
标灰跟米色都是百搭的首先考虑这两个把

作者: ckyellow 时间: 2011-5-27 21:17
这几天在网上看了很多关于色系搭配的帖子！

米色MM陪银斑DD很多人都说可以！不知道是不是真的。还有就是米色猫猫怎么辨别？

还在迷茫中！点点的麻麻不喜欢米色的耳斑和红色眼睛啊。
