t-SNE visualisation of the ALVE-resolved population structure of the sampled chicken populations. Dimension reduction was performed on a binary matrix of ALVE shared between at least two individuals (n = 581). Samples from each country are coloured black for Ethiopia, red for Iraq and blue for Nigeria. t-SNE was derived using sci-kit learn with Python 3.7 with a learning rate of 15, perplexity of 65, and a maximum of 10,000 iterations to ensure stability
