About us

This project's focus is on researching the L21+ 9919 cluster, who have 459=9-9 and YCAII=19-19. The project is also open to anyone else, from any haplogroup, with two or more doubled multicopy markers, that could indicate a possible RecLOH event. Here are some examples of doubled multicopy markers: 385=11-11 385=14-14 459=9-9 459=10-10 YCAII=19-19 YCAII=23-23 CDY=35-35 CDY=36-36 CDY=37-37 413b=23-23 413b=24-24 One doubled marker is not a strong indication of a RecLOH. Two or more suggest that a RecLOH event has occurred.
