Empty Oocyte (VIDEO)

Caption

Short video showing a oocyte (left) that is losing its chromosomes (in red) during development. Normally an oocyte loses half of its chromosomes in preparation to get the second half from the sperm of the partner. When the Mei1 gene is mutated, the normal process goes wrong and the oocyte loses all its chromosomes.
