None Albinos from breeding two hets... possibile?

Hi.
Do you think there is a possible to get none Albinos (for example) when you breeding Het. Albino pair? Please let me
know if you heard about those ceases. How often can it be?

If you are dealing with possible hets then it is very possible that a clutch results in no visuals (homozygous recessive)

You can even go multiple seasons and still not get anything.

It all comes down to the % het and what you are pairing... as well as chance.

No I thinking about 100% Hets not PH.

its absolutely possible, every egg has a 3/4 chance of not being albino when breeding a pair of hets together

Some people assume when you breed a pair of hets, that 1 in 4 eggs will be albino. It's not the case, each egg only has a 1 in 4 chance of being albino. You could get a whole clutch if albinos technically, but also you could never get one. Its all down to each eggs odds coming up.

It's absolutely possible, I've done it SEVERAL times. I've got a pair of het clowns that I've produced three clutches from now and have never produced a live clown. I know they're hets because 2 clutches ago I did produce a clown that died upon hatching. However I've produced a dozen live babies from this pair and not a clown amongst them. You have a 25% chance PER EGG of producing the desired mutation from a het to het breeding, but sometimes the odds just aren't in your favor. If odds had held firm, I'd have 3 clowns from this pair by now.

Aaron, this is actually untrue. You either have 100% hets or you don't. The percentage of the parental stock has nothing to do with chance. You can however, miss on hitting even with 100% hets. You can actually miss on albino to het if you're really unlucky.

As everyone else said, very possible. I got zero albinos from a het to het pairing last year.

I got 0 albinos from an Albino x het Albino! Gotta love those odds! :) 8 het Albinos though! lol

:banana:

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 :bow: 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:mad: And my odds were 50% on hitting a visual. It happens, better luck next season.:gj:

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:rage:

Yes no visuals is possible
