Can someone please explain?

It is my understanding that Scottish Folds should be mated with only American Short Hair or British Short Hair (CFA) and I would assume that Scottish Short Hair are also allowed under GCCF...right?

This is to avoid mating two SFs together which can cause genetic defects...right?

So, in terms of pedigree, any of the above three matings are considered "Pure" (in other words, registerable in most registries) - right?

Therefore, if both parents were to carry the fold gene, the likelihood that the offspring will have genetic defects is very high - right?

The end result is that most reputable breeders will NEVER have an SF x SF mating - right?

Pussy has stated in her previous posts that her starting price for kittens is RM1k, neutered, pet quality. Pussy is also a registered breeder of SF, Burmese and SSH.

I would then have to assume that ny8z is a registered breeder somewhere as his/her starting price is RM1.5k.

The question is, after all the above, if both parents carry the folded ear gene, wont the offspring carry other, more serious genetic defects?

Can someone please clarify???

I started this thread to protect potential buyers from buying offspring of Scottish Fold X Scottish Fold because at least 1 in 3 of the Scottish Fold offspring produce from this mating will suffer osteochondrodisplaysia or deformity of bone and joint of the lower limbs and tail.

Let me explain. Fold gene, Fd is dominant gene. Cats only require 1 FD to have folded ears.

Cat with 1 FD gene are Heterozygous to Fold gene, is genetically, FDfd.

Cats will 2 FD also have folded ears but they will suffer also from deformity of bone and joint. They are Homozygous to Fold gene, is genetically, FDFd.

Scottish Shorthair i.e. Scottish kittens without folded ears, don’t have FD gene, is genetically, fdfd

Ny8z so called mixed Scottish Fold are FDfd and pure Scottish Fold are FDFD.

Mating between 2 Folds have the following possibilities:

1. FDfd X FDfd = 25% FDFD, 50% FDfd, 25% fdfd.
That mean 75% of the kittens are Scottish Fold and 25% Scottish Shorthair. Among the Scottish Fold offspring 1/3 FDFD and 2/3 FDfd. 1/3 of the Scottish Fold will suffered from deformity.

2. FDFD X FDfd = 50% FDFD and 50% FDfd. All offspring are Scottish Folds but 1/2 will be FDFD or suffered from deformity.

3. FDFD X FDFD = 100% FDFD. All offspring are Scottish Folds and suffered from deformity.

The recommended mating for Scottish Fold is with Normal eared cat (Scottish Shorthair, British Shorthair and American Shorthair)

FDfd x fdfd = 50% FDfd and 50% fdfd
1/2 healthy Scottish Fold and 1/2 Scottish Shorthair

I wouldn't risk buying from Ny8z as you don’t normally see the problem until months or ever years later.

Ny8z, lets hear your knowledge about Scottish Fold.

alamak very the 'medic/biology' explanation laa
akekek

i tried to understand the gen details from pussy

tapi saya hanya perlu ingat fold xleh kawin fold

Thanks Pussy - that makes it clearer.

So when you register your kittens, the ones with folded ears are registered as Folds and the ones without are Scottish Short Hair - right?

No Faieza,

There will be no problem breeding curl with curl. Curls is one of mutation breed which do not have any mutation related disease.

Since 1983, AC breeder crossing AC to AC without any problem. That is why in the first place CFA accept AC in a very short time.

Most of the AC breeder breed heterozigous dominant cat and without problem.

With regards to Munchkin, dwarf gene is known to be dominant, but you can't get a heterozygous dominant munchkin, as when both dominant gene co-exist in one kitten, it will be absorb even before born, which mean it will not gave out any problem kitten. So basically you will get a small litter.

Thank you all for your support. We have discussed the issue before under http://www.kitten.com.my/forum/thread658.html

Please don't support breeders who delivery jeopardizes their cats and kittens’ health and well being for their own benefit.

*LOL*
Assuming you're a breeder, I'm beginning to think that you're just threatened by me. Why else would you be so worked up over my ad? You don't know anything about my cats in terms of their background etc. Yes i am a certified breeder and all my cats are registered. So what do you have to say about that now? Look, i can see that you love cats and all, and i respect that, but PUSSY, find something better to do with you spare time. Improving your english could be a start..
Take care guys..

Personal attack is an act of a coward

what cats' body certified your cattery? All I can see in your ad that you just mention that scottish folds wins something. Your ad could be misleading because people would assume that your cat actually won that award.

and its clear that you are into money making because u assume that Pussy was afraid of competition. A true ethical breeder wont breed for money. You just might be another back yard breeder.

probably that cat you sell is just another uncertified cat sold at pedigree price. Duit haram tau menipu orang.

My God, you still don't know why I started this thread. You abused me and now you are criticizing my English. This just shows what sort of person you are. Once again in plain English, I am only against people breeding Fold to Fold. I am not against anyone breeding Scottish Fold and you are the least threat to me.

Perhaps, you could answer the following questions.
Who are you?
What is your cattery?
Which cat association/ fancy you are with?
Did you register your Scottish kittens? Perhaps you could attach their cert.
Who supplied you the Scottish Fold?
Are you still going to breed Fold to Fold?
