Free Picture: Livestock Sperm Cells
|
Description
Scott Bauer photograph of Lawrence Johnson, who is at the Germplasm and Gamete Physiology Laboratory in Beltsville, Maryland, has developed a system for sorting batches of livestock sperm cells based on the amount of DNA they carry. Sperm cells carrying the Y chromosome produce males, while sperm carrying the X chromosome produce females. The X-bearing sperm carry more DNA, which can be measured using a fluorescent dye and a laser. Based on the light they emit, the X and Y sperm can be collected in separate tubes.
