The black fur allele has fitness costs but also confers higher immunity against canine distemper virus, making mix-and-match mating key to population survival.
Researchers tracked the movements of endangered caribou and sequenced a portion of their genomes to determine which genes may influence migratory behavior.
Splitting Chinook salmon into two groups based on their DNA could aid conservation efforts. But some researchers argue that this would be a misuse of the data.
From fish harvests to cottonwood forests, organisms display evidence that species change can occur on timescales that can influence ecological processes.
Immunoglobulin genes might have evolved much earlier than previously expected, perhaps even in the common ancestor of Cnidarians and Bilateria, a study suggests.
