The paper shows that hexaploid Carassius gibelio females use achiasmatic meiosis to produce clonal eggs, while males have reduced fertility due to meiotic issues, and B chromosomes are stably inherited as univalents.

The paper examines sex-specific gametogenesis in natural and lab-bred Fundulus hybrids, finding that females can produce diploid and tetraploid oocytes with clonal reproduction, while males show meiotic failure and sterility.

The paper identifies sex-linked markers in the Australian frog Platyplectrum ornatum, revealing two distinct population clusters with different sex-determining systems.
