What approximate offspring ratio is expected when breeding a Yellow Belly to a normal ball python?

Roughly 50/50 split between normal offspring and single-gene Yellow Bellies

Understanding the co-dominant nature of the Yellow Belly gene is essential for predicting breeding outcomes. When a carrier (one copy of the gene) is bred to an animal lacking the gene (a normal ball python), the genetic segregation follows standard Mendelian expectations for a heterozygous cross. Each offspring has an equal chance of inheriting the normal allele or the Yellow Belly allele from the carrier parent. Therefore, the expected outcome in a large clutch is approximately half the offspring displaying the normal phenotype and the other half expressing the visual Yellow Belly trait, with no Super Yellow Bellies produced in this specific pairing.
