Identical twins on trial: can DNA testing tell them apart?

Identical twins share identical DNA, making standard forensic DNA testing unable to distinguish which twin committed a crime, though whole-genome sequencing can identify rare post-birth mutations to differentiate them.

Is a 'selfish gene' making a Utah family have twice as many boys as girls?

Such sex 'distorters' have been discovered - and studied in great depth - in laboratory animals such as mice and flies, in which their effects can be detected through selective breeding. 'If you look, more often than not, you find them,' says Nitin Phadnis, an evolutionary geneticist at the University of Utah in Salt Lake City, who co-led the study.
