Color morphs in ball pythons (Python regius) provide a unique and largely untapped resource for understanding the genetics of coloration in reptiles. Here we use a community-science approach to investigate the genetics of three color morphs affecting production of the pigment melanin. These morphs—Albino, Lavender Albino, and Ultramel—show a loss of melanin in the skin and eyes, ranging from severe (Albino) to moderate (Lavender Albino) to mild (Ultramel). To identify genetic variants causing each morph, we recruited shed skins of pet ball pythons via social media, extracted DNA from the skins, and searched for putative loss-of-function variants in homologs of genes controlling melanin production in other vertebrates. We report that the Albino morph is associated with missense and non-coding variants in the gene TYR. The Lavender Albino morph is associated with a deletion in the gene OCA2. The Ultramel morph is associated with a missense variant and a putative deletion in the gene TYRP1. Our study is one of the first to identify genetic variants associated with color morphs in ball pythons and shows that pet samples recruited from the community can provide a resource for genetic studies in this species.

Previous models of sexual minority orientation identity development have theorized disclosure of current orientation as important in accepting one's sexual minority identity. Furthermore, research into disclosure of sexual orientation highlights positive outcomes for disclosure and negative outcomes for concealment of sexual minority identity. These models, however, fail to incorporate the socio-cultural context of the individual. Using a grounded theory approach, we conducted 40 interviews with individuals who identified with a sexual minority identity living in rural areas in Oklahoma, a primarily socio-politically conservative state in the U.S. Data collection continued until thematic saturation was reached. Three main themes were identified by participants in regards to navigating disclosure of sexual orientation: (1) assessment of consequences to disclosure; (2) situational disclosure of sexual orientation; and (3) disclosure of current sexual orientation. Rural sexual minority men navigate disclosing their sexual orientation by considering the socio-cultural environment where they live and the acceptance and/or rejection of important individuals in their lives. This consideration demonstrates the importance of considering disclosure as a step in sexual minority identity development, not actual disclosure of sexual minority identity. A preliminary model of navigating disclosure is proposed and implications are discussed. [ABSTRACT FROM AUTHOR]
