Description
Emilie Etoundi and colleagues published a 2024 study of reproduction in freshwater clams. Some clam lineages reproduce sexually. Others use a strange cloning method. Males discard the mother's genes and copy themselves. These clams make sperm without halving their DNA.
The team tracked DNA in developing sperm cells. A sexual species showed the normal halving process. The cloning lineage skipped the expected stages. Its sperm kept the full DNA set. That change explains how fathers produce near copies. Understanding this switch illuminates how asexual lineages begin. It also raises questions about their long-term survival.
