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.
A molecular coancestry
approach (Nomura, 2008)--also implemented in NeESTIMATOR--was used for estimating [n.sub.eb].
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 .
The decrease in reproductive population size may modify mating patterns by increasing selfing and correlated mating, resulting in higher coancestry
and lower effective size within progeny.
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.
Improved percentage of younger individuals, coancestry
mating style were the usual methods used to change the levels of inbreeding (Bijma et al., 2000; Sonesson and Meuwissen, 2001).
1983: Estimation of the coancestry
coefficient: basis for a short-term genetic distance.
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
