hemiclonal

inheritance where one genome is passed on unchanged but the other is replaced in each generation, e.g. in the Poeciliidae Poeciliopsis monacha and P. lucida produce an all-female hybrid called P. monacha-lucida. The hybrid produces haploid eggs containing only the monacha genome, the lucida genome being discarded. The unisexual fish mate with male lucida, the lucida sperm is incorporated into the egg which then contains a clonally-inherited monacha genome and a new lucida genome (Dawley, 1989)
