One corretion Genes/alleles occur in a locus and can be shared by other alleles that are are co-com ie. Montly and stripe corns the montly allele (gene pair) shares the same locus as the stripe allele. This makes it possible for a snake to be het for both Montly and stripe though, the montly gene is Dom to stripe thus the snake will look like a montly.Originally Posted by jhall1468
the Pastel gene has it's own locus but the gene is co-dom to normal thus showing a partial effect on the snake.
