Aim of this project The aim of the Healy DNA project group is to research common dna between members and to distinguish the DNA differences between the different Healy branches. Known branches are the county Sligo and county Cork branches and the county Kerry branch. It is likely that the county Kerry and county Cork share the same DNA. What can you do here? Ask questions. Collaborate on your research. Share knowledge you have gained as you've done your own research in a specific area.
