Supergenes and Sparrows with Four Sexes

Supergenes are groups of tightly-linked genes that influence suites of traits relevant to fitness. While long a fixture of evolutionary genetics theory, their role in empirical studies of non-model organisms has been relatively limited, due to limitations in both our … Continue reading
