Figure 3From: Coexistence of diploid, triploid and tetraploid crucian carp (Carassius auratus) in natural watersThe ovarian microstructure of different ploidy CC. (A) The ovarian microstructure of 2nCC. (B) The ovarian microstructure of 3nCC. (C) The ovarian microstructure of 4nCC. Bar in A-C, 0.02 mm. As the figure shows, the ovaries of three forms of CC with different ploidy entered III-stage, indicated that the females of three kinds of CC were fertile.Back to article page
