A chromosome-level reference genome assembly reveals extreme loss of Y-chromosomal diversity in the Saimaa ringed seal (Pusa saimensis)

Emmi Olkkonen, Ari Löytynoja, Zsófia Fekete…·Jaakko Pohjoismäki

The paper uses a chromosome-level reference genome to analyze Y-chromosomal diversity in Saimaa ringed seals, finding extreme loss of diversity compared to other ringed seal populations.
