Reproductive isolation of inter-specific crosses between Argopecten irradians and Argopecten purpuratus
摘要
Abstract
Inter-specific crosses were conducted between Argopecten irradians and Argopecten purpuratus. Bidirectional fertilizations and successful hatching were examined for all crosses and no prezygotic isolation was observed. The success of hybridization was confirmed by ITS1 maker. Through the observation of H. E. Staining paraffin slice of the gonad of mature hybrids , male gonad was found obsolescence without any active sperm while female gonad was developed with abundant normal appearance eggs. But the hybrids eggs could not back-cross with the parental species, exhibiting typical postzygotic isolation-hybrid sterile.关键词
