Bad odds?

lbrat Dec 01, 2010 08:23 PM

I received an e.mail the other day from a gentlemen who I had sold a female het. blonde T.P.R.back in 07. He bred her for the first time this year to a blonde male and got no blondes out of 8 eggs.Understandably he questioned weather the female was an actuall het.At the time I had only a normal male and two blonde females that were breedable.My biggest female blonde never threw a good clutch of eggs the smaller blonde female went gravid and layed 6 eggs which of course all hatched normal looking hets.One of which said gentlemen bought.There could have been no mix up on my end as I have only ever hatched that one clutch of T.P.R.'s
Has anyone ever heard of not hitting a color morph from a het. x visuall?
The breeding pic is in my other post below.I provided him with that pic and also a pic of the blonde female laying eggs.I have no other means of proof.
Any thought on this situation would be greatly appreciated.

Well, since a visual homozygous x het outcome is only a theoretical 50% visual homo offspring, it does happen now and then. It can happen fairly often the smaller a clutch is too if you think about it, even though the odds are the same. I would expect to see some out of eight eggs, but sometimes the number odds are far opposite of what one might expect. I would assume that after another similar-sized clutch is laid by these same parents, things would turn around and there would be some blonde's in it. After all, flipping a coin 10 times, it certainly doesn't always land on heads 5 times, even though it should theoretically. sometimes it is more, sometimes none, that is simply how it works once in a while.

Hope things go better the next time around......they would almost HAVE to!

Like Bob said, it's the same as flipping a quarter 8 times and getting all heads or tails. (Anyone here ever played Yatzee and got one? -- this wouldn't be far off from that except your dice would be two-sided.)

If you look below you will see my response, to him, on the situation.
One clutch of eight eggs (eight good eggs by the way....I wonder how many slugs there were) you would think you would get at least one or two blondes but things happen...I just don't think he has enough evidence to suspect anything other then bad luck.
If you bred a normal to a blonde then they would/should all be normal het blonde. So, you didn't do anything wrong selling them as het blonde.
I think he just needs to fatten her up, breed her again and see what happens.
