Homozygous for leo^t1 and lof^dt2. Obtained from a dealer and kept by raising mixed eggs from different egg lays of well-laying females. leo^t1 is a recessive mutation causing spotting in adult fish, also known as tup. lof^dt2 is a dominant homozygous viable mutation causing long fins. This is not the line used in the Sanger zebrafish sequencing project.
