Once the Robson DNA samples have been collected, the Y-chromosomes will be compared. Twelve markers – stretches of DNA from different parts of the chromosome where variations from person to person are known to occur – will be compared to see how many volunteers, if any, share the same variations.
Examining these variations in genetic coding is a reliable way of identifying whether people share a common ancestry – if one person shares the same variations as another then they have inherited these variations from the same ancestor.
“We are investigating whether the modern Robsons have a genetic root that leads them back to one original family,” explained Dr Alix Groom, who is leading the analysis. “Just like a surname, the Y-chromosome is passed down from father to son.”
Organisers are hoping to attract one adult male from any interested Robson family to supply a mouth swab at the Centre for Life on November 25 2006. Scientists will take samples from 10.30am until 12.30pm in the Centre’s Conference and Banqueting Suite.
The results of the DNA testing will be announced in the new year and participants will be invited to see the exhibition at its official opening in March 2007. (The results will be for the group, not individuals.)
“The Centre is in the middle of a £4.5million redevelopment programme – when finished next spring, it will house a new permanent exhibition called Human Life. The Robson Encyclopaedia will be part of it,” said Ms Conlon. “We hope that by engaging local people in the development of the new exhibition it will encourage better understanding of what the Centre is all about.”
