Polymorphic Male Color Morphs Visualized With Steroids In Monomorphic Females: A Tool For Designing Analysis Of Sex-Limited Trait Inheritance, Mats M. Olsson, Mo Healey, Mark Wilson, Michael Tobler

Faculty of Science, Medicine and Health - Papers: part A

In diploid animals, males and females share most of the genome (except sex-specific elements, such as sex chromosome genes), yet despite sharing the underlying genes that hard-wire traits, males and females may differ in their phenotypes when traits are controlled by proximate mechanisms, such as hormones. In color polymorphic species where coloration is only expressed in one sex, the design of studies of the inheritance of color and coevolved morph-specific traits (e.g. territorial vs sneaker strategies, skewed energetic investment in territorial defense vs sperm production, etc.) is compromised as the expression of morph-coding genes is only visualized in one sex. …
