None Albinos from breeding two hets... possibile?

[Stewart_Reptiles]

Sure there is a chance that no visual is produced when pairing two hets together, remember that your chances to produce an albino is 25% per egg.

Sometimes people will not produce any visual and sometimes people will produce several, depends on your luck.

Personally I would give a pair 3 seasons to prove before I write that pair off as het.

Yeah its entirely possible.... I have seen the same visual male albino and proven het female throw a clutch of all hets 2 years in a row...... bad luck and crappy odds yes... but it has happened with a visual to het breeding so het x het is even more likely to not pan put

Now I see it's more often than I thought. Hope to have more luck in next year Thanks for answers!

It happens to EVERYONE who breeds sooner or later, it's just that people tend not to brag about getting crappy odds.

Just a case of bad luck
Best of luck to you next year!

Yep--out of a 13 egg clutch, once, i got 11 pastels and 2 normals. It could JUST as easily have been the other way around. It's not at all strange for a het X het breeding to produce no visuals.

To formula to figure the odds of completely missing is (1 - p)^n where p is the odds of hitting per egg and n is the number of eggs. For example for a 6 egg clutch from het X het (i.e. p = 1 in 4 or 0.25 and n = 6) the odds of not producing any albinos is (1 - 0.25)^6 = 17.8% or about 1 in 5.6. This could help you gage how unlucky you would have to be to miss or if something else is going on like one of the parents not being a het or parthenogenesis.

Here are the odds of missing per clutch size for het X het:



eggs chance missing
1 75.00%
2 56.25%
3 42.19%
4 31.64%
5 23.73%
6 17.80%
7 13.35%
8 10.01%
9 7.51%
10 5.63%
11 4.22%
12 3.17%
13 2.38%
14 1.78%
15 1.34%
16 1.00%


Here are the odds of missing from homozygous X het:

eggs chance missing
1 50.00%
2 25.00%
3 12.50%
4 6.25%
5 3.13%
6 1.56%
7 0.78%

Like everybody else already said, you have a 75% chance of hitting a non-visual. Two seasons ago I bred a Cinnamon to normal, 5 eggs, 5 NORMALS. My second clutch was Pinstripe to normal, 5 eggs, 5 NORMALS And my odds were 50% on hitting a visual. It happens, better luck next season.

Every breeder has their bad odds story, I like when it happens early in the season so I can get them out of they way
My worst odds was on a bumble bee project years back, Pastel to Spider, 3 clutches- 18 eggs, 1 egg died, 9 normals, 4 pastels, 3 spiders, 1 bumble bee

Same odds to see a normal as a bumble bee

Yes no visuals is possible
