ok so say I breed 2 100% het for pied balls will 1 out of 4 be
pied?sorry just new to the whole het deal.
Thanks,
Casey

You're right, but the 25% is just what happens on average. You could get anything from all pieds to no pieds. The larger the clutch you have, the more your chances for pieds increases.

ok so how offen do'es a no pied clutch happen out a pair 100%
het pair?
Thanks

It varies... the only thing that 100% het x 100% het guarentees is that EACH EGG has a chance of being the homozygous recessive morph.

It's not a matter of 1 in 4. But if you were to have 4 eggs, more than likely at least one should be the homo recessive trait.

Hope that helps a little.

With het X het the 25% chance applies independently to each egg. The idea of the perfect four egg clutch that falls into these odds is a bit of a misapplication of the Punnett square (applied to a clutch and not to each egg as intended).

Linked is a table that shows your odds of getting at least one homozygous egg from given het X het clutch sizes.

I wonder what the chart would look like with double hets? But some double hets are not proven as of yet so no one would know if they hatch what they intended to hatch. We all know what an albino looks like. Hope some unknowns are hatched this year. Like the albino pied.

eggs are in the clutch. Since each egg has a 25% probablility of being a pied, your odds go up as your clutch size goes up.

Here's a good experiment for you.

Take 2 quarters and flip both of them. The results of the flip will represent one egg from a 100% het to 100% het breeding. Designate both heads as a pied, both tails as a normal and a head and a tail as a het.

Now, if you have 6 eggs in a clutch, just flip the 2 coins 6 times (one time to represent each egg). Write down your results as pied, normal or het. These results represent one 6 egg clutch possibility.After doing this, do it again, and again(6 sets of 2 coin flips each time) and you will get many different possible 6 egg clutch results. You could even get 6 pieds in a clutch of 6, but that won't happen very often!

Try it again with just 2 sets of 2 coin flips to see how many pieds you get in a 2 egg clutch. Again, you should try this many times to show that you will get many different results. So there is no definitive answer to your question.

Consider that it is even possible that you could produce 75 normal looking animals in a row, then sell your breeders to someone who then could produce 25 pieds in a row! Not too likely, but it is possible.

My het pied did the following:
2001 4 eggs 3 pieds
2002 5 eggs 2 pieds
2003 no eggs Booooooooo
Not too bad in odds

BTW the other pair

2001 none
2002 none
2003 no eggs [4 bad]

fun? 12k no pieds!!!!!
bad odds
