In female chickens, the left gonad develops to become the functional ovary whereas the right gonad remains rudimentary. The germ cells in the female left gonad accumulate in the gonadal cortex and start expressing the meiotic markers H2AFX (red) and SYCP3 (green). Melo Bernardo et al. (this issue) investigated the asymmetrical distribution of female chicken germ cells during development, and found a sex‐independent preferential migration of germ cells to the left gonad, followed by a pronounced meiotic wave from the cortex center to the extremities without unusual levels of apoptosis in the medullary germ cells.
