The genetic architecture of dewlap pattern in Hispaniola Anoles (Anolis distichus)

Color and pattern are often critical to survival and fitness, but we know little about their genetic architecture and heritability in groups like reptiles. We investigated the genetic architecture for the pattern of the dewlap –  an extensible throat fan important for communication – in anole lizards. We studied the Hispaniolan bark anole (Anolis distichus) – a species that exhibits impressive intraspecific dewlap polymorphism across its range – by conducting multi-generational experimental crosses with two populations, one with a solid pale yellow dewlap and another with an orange dewlap surrounded by a yellow margin. Upon rejecting the hypothesis that the extent of the orange pattern is a quantitative trait resulting from many loci of minor effect, we used a maximum likelihood model-fitting framework to show that it is better explained as a simple Mendelian trait, with the solid yellow morph being dominant over the blush orange. The relatively simple genetic architecture underlyi..., , , # **Data from: The Genetic Architecture of Dewlap Pattern in Hispaniola Anoles (*Anolis distichus*)**

### Supplemental Data

Supplemental data includes a spreadsheet with the raw data of the proportion orange dewlap area for each anole image and transformed data. Each generation is described as follows:

P ign: Wild caught *Anolis distichus ignigularis* which were representatives of the parental population

P rav: Wild caught *Anolis distichus ravitergum* which were representatives of the parental population

F1: Hybrids of the two species reared in lab

F2: Hybrids of the F1 population

BC1: Backcross between F1 individuals and *A. d. ravitergum*

BC2: Backcross between F1 individuals and *A. d. ignigularis*

Column headings for the spreadsheet are defined as:

BC 1: The number assigned to the BC1 individual

Label: Image label for the individual

Dewlap Area: Measured area of the dewlap (cm^2)
