HVS-I Identity by Descent or by State
A theoretically evolving tree is presented. Coding-region polymorphisms are in black. HVS-I polymorphisms are in red. Samples A and B share HVS-I haplotype 16303 by descent. Samples A and D or B and D share HVS-I haplotype 16303 by state and as a result of homoplasy. Samples C and E are identical by state as a result of a back mutation in position 16303 in sample C as marked by the “BM” designation.
