aFour focal northern elephant seal harems (column headings) with the alpha male shown in brackets. The percentage of observed copulations from earlier studies is compared with calculated percent paternities determined by genomic analysis. The significance of the difference was tested using two-sided Chi-square test. The proportional FROH (indicating inbreeding) and loss of function at five identified loci that are associated with male reproductive health are given. Bold text highlights the results for M12.
