Population genetics of east Antarctic sea urchins
Progress Code: completed Statement: Microsatellite data: Some null alleles were detected, with some individuals not amplifying at individual loci. Fertilisation data: After initial collection prior to sea ice breakout, all urchins collected post sea ice breakout had completed their spawning cycle, p...
