  1. IBD = identity by descent; nb = number; T = average generation length in years; EqG = number of equivalent generations; F IS = fixation index; N eCi = method based on individual coancestry rate; N eCt = method based on coancestry rate between two successive generations; N eFi = method based on individual inbreeding rate; N eFt = method based on inbreeding rate between two successive generations ; N es = N e method based on sex ratio; N ev = method based on variance of progeny size; in brackets, minimal and maximal values.
