Genomic evidence for inbreeding depression and purging of deleterious genetic variation in Indian tigers

A. Khan, K. Patel, H. Shukla, A. Viswanathan, T. van der Valk, U. Borthakur, P. Nigam, A. Zachariah, Y. Jhala, M. Kardos, U. Ramakrishnan

This study uses whole-genome sequencing of Indian tigers to show that small-isolated populations have higher inbreeding depression and purging of deleterious alleles compared to larger, connected populations.
