It just means that certain breeders have seletively chosen certain animals to breed together for a certain trait.
So in Snows people generally line breed them to breed out any yellow coloring so that they are all black and white.
Thank you. I looked it up but wanted to make sure what I was dealing with. I have a normal snow which seems to only be developing very light yellow. Probably going to breed him next year and I am trying to figure out which type of giant/super giant morph I am going to get to breed with him. I am leaning on trying to find a super snow super giant.
Line Bred Snow is actually a very specific line of gecko that originally comes from Albey Of Albey's Too Cool Reptiles. It was the original "snow" that was around before Mack, Tug and Gem snows.
Most people Call the Albey line bred snows. true Albey Line Bred Snows have no other type of snow in them. and when bred together do not give you a super snow.
Saying that line bred snows are the selective breeding of Gem, Tug, or Mack snows is technically incorrect.
