Submission + - Scientists Sequence Entire Genome of 91 Sperm From One Man, Vast DNA Differences (medicaldaily.com)
An anonymous reader writes: Scientists have sequenced the entire genomes of 91 human sperm from a 40-year-old man and revealed valuable insights into the infinite genetic variation that naturally occurs in a single individual.
Researchers at Stanford University said that the study, published in the journal Cell, is the first to completely map out the whole-genome of a human gamete, cells passed by parent to offspring that determine a child's physical characteristics.
The latest findings confirmed what scientists already know, that every sperm is different because of the way the DNA passed down from a parent is shuffled in the process known as recombination.
