Haplotype network of ancient Norwegian haplotypes. Median-joining network of ancient Norwegian haplotypes showing their genetic relationship and frequency at different time periods. Yellow: bottleneck period (c. 500–1,500 yr BP), green: pre-bottleneck period (c. 2,000-2,500 yr BP), blue: Mid-Holocene (c. 3,500-7,000 yr BP). Size of the circles is scaled according to the frequency of sequences.
