Big Black Conda is a mix of the recessive sable mutation, the heterozygous incomplete dominant arctic mutation and the heterozygous incomplete dominant anaconda mutation. This combination gives the snake the brown sable colouration with darker borders around the saddles and visible eyebrows. With younger snakes the arctic mutation seems to give a more lighter colouration with more reddish and greenish hues. With age the snake will get darker and the saddles will get black. The anaconda mutation gives the snake a lack of pattern.
