Professor Alec Jeffreys’ research is focussed on understanding human DNA diversity and exploring processes that generate variation in the human genome.

DNA Fingerprint
DNA Fingerprint

His early work on minisatellites not only resulted in DNA
fingerprinting, for which his laboratory is best known,
but also opened up major areas of enquiry into human
genome dynamics which remain the focus of much of
his and his colleagues’ activity. Current areas of research

Patterns and processes of human meiotic recombination,
including understanding how recombination hotspots are
specified and how they evolve as highly dynamic entities
in the human genome.


Ectopic recombination and genome instability.
Unequal crossover is a major process creating copy number variation in the human genome, often with pathological consequences, and is being directly explored by detecting
de novo rearrangements using single DNA molecule analysis.

Base mutation. Prof. Jeffreys’ group is also developing methods to allow the direct detection of rare de novo base substitutions in the human germline and to explore the relationship between mutation and recombination.
