Single-gene trait/disorder: yes

Mode of inheritance: Autosomal

Disease-related: no

Key variant known: no

Inheritance: Pirani et al. (2025) "studied the dewlap of the slender anole (Anolis apletophallus) which exhibits a dewlap polymorphism: males have either an entirely orange dewlap ("solid" morph) or a white dewlap with a basal orange spot ("bicolor" morph). ... [The authors] findings indicate that the slender anole dewlap polymorphism is best explained as an autosomal, single-locus, Mendelian trait with the solid morph allele dominant to the bicolor morph allele." 

Mapping: Pirani et al. (2025) "identified a region strongly associated with this [dewlap] trait and within this region [the authors] identified a promising candidate locus-the transcription factor single-minded 1 (SIM1)-that may underly the dewlap polymorphism."
