Haplogroup I1 > M253
DNA
Haplogroup I1-M253 is described in a Wikipedia Article. A study of the genesis and spread of Halopgroup I and its clades is on this page: Nordtvedt's Haplogroup I Tree and Conjectured Spread Map.

Haplotype Table

A modal haplotype is the set of markers corresponding to the most frequently observed values for each marker. The markers highlighted are said to be off modal and patterns in these markers distinguish one branch or family from another.
The Basic I1* modal haplotype in the table below is from the I1modalities.xls spreadsheet of Nordtvedt. There are many subclades of I1 and upgrades to 67 markers in concert with SNP testing to better classify the individual haplotypes in the table below. Persons herein are advised to join the yDNA Haplogroup I Subclade I1 project for that purpose.

Genetic Distance

Genetic distance is a measure of the differences between two haplotypes. In its simplest form one simply counts the number of markers that differ. The model used is known as the Hybrid Mutation Model and conforms to that used by Family Tree DNA.

Time to Most Recent Common Ancestor

The Time To Most Recent Ancestor (TMRCA) is a measure of relatedness and well defined in the case of a family tree wherein one simply counts the number of generations back to the most recent common ancestor shared with someone else in the tree. From differences in haplotypes between two men it is possible to make a rough estimate of the probability that the TMRCA falls between two numbers. The numbers reported in the table below are such that the TMRCA is expected to fall within the range shown with a probability of 90%.
