Genetic variants in Alzheimer’s- and smoking-related genes appear to be under selection pressure, according to a study comparing the genomes of old and young participants.
For two decades, scientists struggled to fully sequence the Y chromosome. Finally, researchers have mapped its full length thanks to recent advances in sequencing technology.
Researchers made the find using an algorithm that purportedly distinguishes between mutations that were selected for and those that came along for the ride by coincidence, a feat that has long eluded scientists.
