albino genes

evercraig190 Oct 23, 2005 02:17 PM

ok, i have a question, some guy keeps trying to tell me that when you breed a albino x normal you get 100% hets...i thought you would get 50% hets....and albino x 100% het gets albino, 2-100%(66%) and 1 normal...if anyone can clarify without wasting to much of their time i would appreciate it...thanks...

Albino x Normal = all 100% hets.

Albino x 100% het = roughly half albino half het (all normal looking would be het)

100% het x 100% het = roughly one albino, 2 hets, 1 normal (all normal looking would be considered 66% possible het)

Correct me if I'm wrong.

to each individual egg as far as the odds go, not the clutch.

Breeding a homozygous recessive (albino, piebald, hypo, axanthic, clown, etc) to a normal or a different morphs will produce all hets for the trait.

Breeding a homozygous recessive to a heterozygous individual will produce eggs with an equal chance of being homozygous recessive or heterozygous. This is where people say that in theory you should get half albinos and half hets.

Breeding 2 heterozygous animals will produce eggs with a 25% chance of being homozygous recessive, a 50% chance of being heterozygous, and a 25% chance of being homozygous dominant(normal). That's where you get your 66% possible hets.

Breeding a heterozygous snake to a homozygous dominant(normal) will produce eggs with a 50% chance of being heterozygous and a 50% chance of being homozygous dominant(normal). This is where you get your 50%.

I'm not going to get into the 25% business but if you ask me, odds wise, they do exist. They just wouldn't be worth anything more than a normal.

Hope this helps more than it confuses, I just wanted to clear up the idea that a het to het breeding will produce a homo recessive, as you could get a 7 egg clutch and no albinos.

albino to normal equals all 100 % hets

albino to a 100 % het equals all 100% hets and albinos..
