Default 66% hets

Ok i dont get where people get 66% hets from
if 66% is 1/3 of a chance of it being a het then why isnt it called a 33% het
as
66 x 3 = 198
33 x 3 = 99
So wouldnt it be a 33.3333333333 % het?

Doesn't it mean it's got a 2 out of 3 chance of carrying a het?

As you said a 33% het is 1/3 chance of being a het, which is why 66% is 2/3 chance of the same.

Using a standard example of two simple ressesive hets bred together and using a punnet square thingy, you should get one visual, two hets and one normal. Seeing as you can't visually discriminate between the two hets and the normal, and two of the three ARE hets, they are all classed as 66% hets...

Faith is thinking about maths! - not all of the babies when hets and visuals are present are counted as the 100%. The visual babies are not included in the 100% as they are not hets - they are 0% het as they are homozygous! Just don't think about it too much!, it hurt my head - just smileand agree that its 66%

66%'s are pointless anyway, why bother?

But yeah, it's like everyone said Faith, from the '4 egg rule' with a recessive or het put to a recessive or het, you will get 1 visual, 2 100% hets, 1 normal, the two hets are indistinguishable from the hets so you class them all as 'possible' hets, givin you the 66%.

I disagree that 66% hets are pointless.

IF you can find a breeder willing to sell the whole clutch to you then they can be a great way of getting into something you wouldn't ordinarily be able to afford.

Pointless for low end stuff, worth a crack if you're priced out of 100% hets or visuals.
