The core of this project assesses gene flow between wild and domesticated turkey populations through population-genomic and ancestry analyses. Deoxyribonucleic acid (DNA) will be extracted from 28 turkey samples, followed by ancestry analyses to quantify hybridization patterns. Increasing anthropogenic pressures, including landscape modification, the expansion of invasive species, and climate change, can elevate rates of interspecific interactions and hybridization beyond natural levels. Such interactions are particularly concerning when domesticated and wild forms lack reproductive barriers, creating conditions for widespread introgressive hybridization. By characterizing the timing, extent, and frequency of gene flow across the genome, this work provides critical insight into evolutionary dynamics and conservation risks that are difficult to observe directly in natural populations.
