Hi can someone explain the het senario for me . If u had 100% het & if you were to cross with a normal what would the offspring be?
cheers

Someone should make a sticky about this. Like you said Wokka, it can be deceiving when you are starting out and you hear about 66% and 50% hets.
Cactus the possibilities of the different scenarios are:
Albino-albino = 100% albinos
Albino-normal = 50% het, 50% normal but all look the same so there's a 50% chance any individual in het
Het-het = 25% albino, 25% normal, 50% het but again hets and normals look the same so of the normal looking ones 1/3 (33%) will be normal and 2/3 (66%) will be het
These are all just probabilities though so you could be really lucky and, for example, get all hets from an albino-het pairing or really unlucky and get none. From what I understand though, it usually comes pretty close to the expected ratios.
What is left out of the 50% and 66% het is the words "chance of". Those animals may in fact not be hets. Some people think it is a deceptive description. To be correct 66% het should be described as a 66% chance of being hetrozygous( and therefor 33% chance of being normal); and 50% het, as 50% chance of being hetrozygous ( and therefore 50% chance of not being hetrozygous ie. normal)
i had no idea hets were a recessive only thing!
