A low coancestry coefficient among the Argentinian materials compared to cultivars from other Latin American countries was confirmed more recently by Giarrocco et al.
Briefly, top-yielding families from each cohort were crossed by pair matings between individuals from unrelated top-yielding families with low coefficients of coancestry ([[theta].sub.ij] < 0.
The average inbreeding and coancestry in the reference population were 0.07 and 1.56%, respectively.
The random [u.sub.i] effects are assumed to follow a normal distribution with a mean zero and variance-covariance matrix [[sigma].sup.2.sub.u] G, with G = 2K, and K is the coefficient of coancestry matrix between RCSLs.

The rapid advances in genome sequencing and high-through put DNA techniques have led to new and more precise measures of genetic diversity and coancestry and inbreeding coefficients [62].
The characterization of spatial distribution of genotypes inside the population was carried out using the coancestry coefficient ([[theta].sub.xy]) between all pairwise individuals within 10 distance classes, based on the method proposed by Loiselle et al.

We used TrioML and DyadML estimators as these allow for inbreeding to be considered in the analysis using the Coancestry software (Wang, 2011).
Genetic inbreeding (F) and relatedness (r) among pairs of individuals, and within and among groups of whales were investigated using COANCESTRY (Wang, 2011).
