70% f2?

Postby egroegart » Mon May 14, 2012 11:20 pm

I was just wondering if it was possible to have a 70% F2 Savannah?

The reason I ask is because a good friend of mine that bought one of our Savannah kittens wants to know. Someone is claiming they have 70% f2's. I am pretty sure that is impossible isn't it?

Yeah. Unlike wolfdogs they are true hybrids so it's a 50/50 cut each time.

f1=50%
f2=25%

Now if you cross the f1 with a full serval then f2=75% But even though it's second generation cross I don't think they count as f2 in the typical sense as that's normally used count towards domestic, not away

Probably not. But percentages can be mixed in weird ways: http://tiamosavannahs.webs.com/highsavannah.htm

Cool that explains the F thing better. I thought it was counting the breedings but seeing how you can have more than one breeding and still be one generation away from the serval clarifies.

Most likely he doesn't have a 70% f2 But the would possible with a 90%+ male and 50%+ female. The male must be around 90% to be fertile according to haldane's rule in order to be feritle. So if they have a 90%+ f1 male savannah and a %50 + female f1 savannah then yes he could have a 70% f2. Getting a male like that would be hard to though and it would require at least 3 serval breedings back to a higher percentage domestic ; and I'm not sure that this has ever been succusfully done.

Thank you for the replies. There is a breeder claiming to have 70% F2's on facebook. I just thought it looked kind of odd. and some things they were saying just didn't add up. I think they may be scammers. I don't know.
