Reptile & Amphibian Forums

Ok... I have been racking my brains here and I have searched the forums, but my eyes hurt and so I thought I would ask the time old question... (and yes I even went to the genetics website - I still had no clue)

What's the difference between ...
100% het for albino
66% het for albino
50% het for albino
possible het for albino...

I really like the albinos and was curious as to what the parents have to be in order to receive those percentages listed above. Please don't be mad at me for asking this question...

I really appreciate any help
Thanks in advance
Jay

ok, i'm no expert but i do know this.het for albino means they carry the gene, but are not albino themselves. if you mate two 100%het for albinos, your chance is 25% of the clutch being albinos...even then it's still possible you won't get any. as you get to 66% and lower, the chances become smaller. most of your clutch will be 100% hets, or regulars. i'm pretty sure im correct on this, if i'm not. please anyone correct me.

hope this helps.

100% het- means that one of the parents was albino, so all of the babies are 100% het for albino. Can happen from normal to albino breeding or albino to 100% breeding.

66% het- means that there is a 66% percent chance the babies are het albino, not sure what pairing would produce this maybe someone else can reply.

50% het- there is a 50% chance that the babies are het albino, from breeding a 100% het to a normal, or two 100% hets together.

Possible het is the same as 66 or 50% het albino. This applies to all recessive genes when using a Mendellian(sp?) square to figure possible offspring.

Hope that is a bit clearer than mud!

100% het is indeed an Albino bred to a normal. All the off spring look normal, but because one of the parents is an Albino the all the babies are Het for (or carry the gene for) Albino

66% Chance for Het is when you breed 2 100% hets together. Say this pairing produces 20 Babies (nice even number) out of these 20 babies 5 of them should be albino and 15 of them are normal LOOKING. Out of the 15 Normal LOOKING babies 2/3’s or 66% of them are going to be het for Albino. So 10 out of the 15 normal looking babies are carry the gene for albino. Problem is, you don’t know which ones they are, so you have a 66% chance of getting a Het for Albino out of the litter.

50% chance for albino is by breeding a Normal Boa to a 100% het. All the babies come out looking normal but half of them carry the Albino gene. Again you have no idea which one carries the gene and which does not, so you have a 50% chance of picking out a Het for albino baby out of this group.

I hope this clears it up

What if I bred an albino to a 100% het...

and does it matter which is the albino...

I mean does the albino have to be a male or female?

I am looking into these lovely animals and always seem to get confused...

Thanks again to everyone who has posted replies...

>What if I bred an albino to a 100% het...

Short answer -- half the babies albino, half the babies normal looking but heterozygous albino (AKA 100% heterozygous albino). This is statistically speaking; the actual result is the luck of the coin toss.

Longer answer -- the albino produces gametes (eggs or sperm) with only the albino mutant gene. Half the the heterozygous albino's gametes have the the albino mutant gene, and the other half of the gametes have the normal gene. Piair the sperm and the eggs, and half the embryos have two albino mutant genes (are albino), and half the embryos have an albino mutant gene paired with a normal gene so they look normal but are heterozygous albino.

>and does it matter which is the albino...

It does not matter. The male can be albino and female heterozygous albino, or the female can be albino and male heterozygous albino. You get the same result both ways.

Thanks everyone for replying, you've been a BIG help!
