This paper is about an ultimate high-throughput single molecule PCR method developed during my post-doctoral stay at the University of Southern California and the Johannes Kepler University. With this technology millions of single DNA molecules can be amplified in parallel on microscopic beads. It has been a turning point for my previously used technical approaches and has opened several other venues of research.

In this work, we studied recombination hotspots and carried out a systematic survey of crossover rates using sperm typing during my post-doctoral stay at the University of Southern California. I developed a very efficient way of counting crossovers using real-time PCR that allowed me to count recombinants in millions of meioses. This work presented an important comparison of population genetics and sperm typing approaches and provided evidence about the possible co-regulation of hotspots of recombination. During that research, I stumbled across the intriguing properties of recombination hotspots.

This work on the paternal age effect was the first to accurately quantify new mutations in human sperm DNA, in the exciting and unconventional work on achondroplasia. It required the development of a very sensitive method that detected a single nucleotide change in a large pool of wild type genomes. It addressed the long discussed topic whether older men have a higher risk of transmitting new mutations. This study was the first to experimentally measure the mutational load on male germcells and pointed to the novel observation of selection at the level of germcells.
