Version type

In embryos of birds have two ovaries, but usually only one of them — left — develops to the point of sexual maturity, the right remains in a rudimentary condition. If, however, the left ovary ceases to function due to illness, or because of intentional destruction in order to experiment, it starts to develop the right, but not in the Mature ovary, and a male egg.
