Average inbreeding coefficients for animals born from 2001 to 2008. Average values of the positive inbreeding coefficients calculated using pedigree ( F
) or marker information ( F
) are represented in this figure. The three marker-based metrics represented here are based on the variance of the additive genotype (F
), the excess of homozygosity (F
) and the correlation between uniting gametes (F
). The number of animals used in each time point is listed below the X-axis.
