There are vertical bars on the peduncle and this type of Cobra Bar Snakeskin is a variation of Snakeskin.

In the IFGA judging system, the vertical bar is considered a fault under the Snakeskin class.

Dr. Violet Phang of Singapore published a research article showing the presence and absence of the vertical bars;

The cobra snake bars are defined by an autosomal recessive gene called bar by Violet Phang. The cobra bar autosomal gene has the property of altering the Y-linked snakeskin pattern. This makes it a kind of gene modifier.

It requires the presence of the Y-linked snakeskin pattern on the male to show. In other words, it does not show on guppies who do not have the snakeskin gene and also does not show on the female.

There is an autosomal gene called Zebrinus (Ze) by Kirpichnikov, but he lists in his table as only expressed by YY males.
