Since subpopulation B has an extremely high average coancestry
and relatively large distances from the other subpopulations (see also Table 1), removal of this subpopulation causes the largest within-diversity ([GD.
NL] of related pairs of lines is a linear function of their coancestry
coefficient (Melchinger, 1993).
Unweighted pair-group method based on arithmetic means (UPGMA) clustering of cultivars was based on modified coancestry
coefficients (Reynolds et al.
The inbreeding coefficient of a 4x-2x hybrid is a complex function of the coancestry
of the parents, the inbreeding of the parents, the coefficient of double reduction in the tetraploid parent, and the frequency of single exchange tetrads in the diploid parent, and depends on the mechanism of 2n pollen formation (Haynes, 1992; Haynes and Potts, 1993).
the largest attainable inbreeding coefficient in the smallest number of generations, and (iii) noninbred relatives related by coancestry
with the inbred relatives under study.
The average inbreeding and coancestry
in the reference population were 0.
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.
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
Improved percentage of younger individuals, coancestry
mating style were the usual methods used to change the levels of inbreeding (Bijma et al.
