You have a puppy whose dam is a Optigen B, sire a Optigen A. What are the odds the puppy will be a A? Thanks

75% clear/ 25 carrier.

Unless you have luck like I do...then you will always seem to end up keeping the Carrier!

Someone needs a refresher course on probability ;)

A bred to B (Clear bred to carrier), each puppy has a 50% chance of being either A or B (clear or carrier).

Here's a pretty chart... http://www.optigen.com/opt9_test_prcdprabs.html

I don't think this is correct. I believe it is 50%/50%.

Nicole is right - 50% clear 50% carrier (statistically speaking) The chart she referenced is easy to understand. The probability is the same as breeding a pure black to a black carrying yellow.

LOL... or a Black carrying yellow to a yellow.... and getting all black puppies in a litter of 9... oh, and they were all males.... you want predictability? Find another hobby.

Beg to differ, Greg - I've found it a very predictable hobby. Experience has taught me that, if I want a black bitch from a yellow/black mating, I'll get 5 black dogs and 3 yellow bitches, So I just opt for a dominant black stud dog and can be reasonably certain of getting..... 9 black dogs!!!

Predictability and probability are two very different "animals". I believe there's Yiddish proverb that says, "Man plans. God laughs." How true!
