All the ways to get a white ball python?

Alleles are two different genes that can make a gene pair. Example: a normal gene and an albino gene. This gene pair makes a het albino snake. Example: a mojave gene and a lesser gene. This gene pair is one way to get a blue-eyed white ball python.

Alleles have slightly different DNA sequences, but they are located in the same place in the genome.

The albino mutant gene and the mojave mutant gene are not alleles. They cannot make a gene pair because the have different locations in the genome.

Hope that helps.

That is not correct, alleles are not different genes. Alleles are different forms of the same gene So, using the Albino as an example, you have two different forms of the tyr gene, one that is fully functional and one that is non-functional. Loop Candy in and you have a third form of the gene, one that is low functioning.

An easy way to think about it is like a flight of cards, ace through king; the face of the card is the gene and the suit of the card is the allele. If we assign the gene for Albino to the 3 card you can then have a pair of 3s that are both spades (WT), a pair of 3s that are both hearts (Albino), a pair of 3s that are spade and heart (het Albino), a pair of 3s that are both clubs (Candy), a pair of 3s that are spade and club (het Candy), or a pair of 3s that are club and heart (Candino).
