R-U198 LYNN PHYLOGENY |
© 2016 John Sloan and Loretta Layman
While all R-U198 Lynns have retained R-U198 values for a number of key markers [DYS] which identify them specifically as R-U198: DF89 excl. type G *, they also carry variations in five other markers which set them apart as a distinct family within that haplogroup. These five marker values are common to all known R-U198 Lynns who have been Y-111 tested (a smaller number of values common to those tested at Y-67 or Y-37). Those values are believed, therefore, to be the ancestral values for those markers in the first branch or new line within the R‑U198 Lynn family, that branch or line having occurred sometime before the earliest known ancestor of any R-U198 Lynn who has tested.
In addition, the mutations illustrated below occurred in one generation or another after the first branch or new line and thus resulted in additional lines within the family of R-U198 Lynns. These changes include two instances in which it is believed that a "back mutation" has occurred; i.e., a marker the value of which first had changed from the R-U198 value and later mutated back to the R-U198 value. While these mutations indicate which R-U198 Lynns are more closely related to one another, none of the mutations are evidence of the relative distance between living descendants of the various lines and their common R-U198 ancestor.
In the following illustration, colors correspond to those on the charts of Y-DNA results (Y-DNA 1-67 and Y-DNA 68-111); except, there are slight color differences here among the three men in the last new line (the YCAiib / DYS549 group), owing to relatively recent changes.
The mutations illustrated above are shared as follows, as seen also in the respective Y-DNA results charts:
The paper trail indicates that Milton is more closely related to Jeffrey and M. Woodward than he is to M. Ch., although Milton and M. Ch. both have the R‑U198 value for marker YCAiib and Jeffrey and M. Woodward do not. The probable scenario is this: the mutation from 22 to 21 at YCAiib occurred in a common ancestor of Milton, Jeffrey, and M. Woodward (an ancestor not shared with M. Ch.) in just the last 7-8 generations; and, then, Milton's line more recently experienced a back mutation to 22 at YCAiib.
