Y-chromosome Inheritance Pattern Pedigree (Paternal Lineages)

Squares with yellow dots represent relatives that share the same Y-chromosome. All individuals with a yellow dot will have identical Y-chromosome DNA profiles. For example, if the male in generation one (on top) had a Native American Y-chromosome haplotype, then all the other descendants with a direct male-to-male connection to him would also have the same Native American Y-chromosome haplotype (i.e., their Y-chromosome would be identical).
