Abstract
To test for a residual maternal influence in the performance of androgenetic offspring in common carp, Cyprinus carpio, an experiment was conducted where three females and three isogenic males were used to produce nine androgenetic families. Eggs were irradiated with UV (175 mJ cm −2) and diploidy was induced using a heat shock (40 °C, 2 min). Yields of androgenetic diploids depended mainly on the egg donor. After raising the larvae for a period of 10 weeks, significant differences were observed regarding the frequency of normal and deformed androgenetic animals, also depending on the egg donor. It is hypothesized that the UV-irradiation causes damage in maternal RNA's, resulting in disturbed embryonic development.
