Super Pewter
Combination
Super Pewter is the hobby name for a ball python with two Cinnamon genes and two Pastel genes, a Super Cinnamon and a Super Pastel at once. Every baby inherits one Cinnamon copy and one Pastel copy, so bred to a normal it gives only Pewters. The two-copy Cinnamon genotype is reported to cause spinal kinking, duckbill facial changes and eye abnormalities.
