Sentence examples for molecular coancestry parameter from inspiring English sources

Relatedness was estimated using the molecular coancestry parameter (f ij ) according to Caballero and Toro [ 72].

In the present study, I propose a new method for estimating the effective number of breeders Neb from a parameter of allele sharing (molecular coancestry) among sampled progeny.

Molecular information was used to: a) construct an artificial pedigree maximizing the correlation between the molecular coancestry matrix and the coancestry of the artificial genealogies (P* Matrix); and b) computing the Ritland's estimator of between-individuals molecular coancestry (R Matrix).

Coancestry is usually calculated from genealogical data but molecular markers can be used to replace genealogical coancestry with molecular coancestry.

Marker information was used to calculate molecular coancestry that replaced pedigree-based coancestry.

Table 1 shows the regression of the genealogical coancestry on the molecular coancestry or the molecular covariance.

Assuming that the allele frequencies are random draws from a Beta distribution with parameters α and β, and Var (p) are α/ and α/ β [2 (α + β + 1)], respectively.Thus, to extrapolate from molecular coancestry or molecular covariance to genealogical coancestry requires that the distribution of the base population allele frequencies is known, or at least its first and second moments are known.

We take advantage of this property to convert the molecular coancestry to the parent-based coancestry (f1).

Molecular coancestry is, therefore, an upward biased estimator of the coancestry relative to an arbitrary base population.

The benefits of using molecular coancestry calculated with dense marker data were small when compared to genealogical coancestry (a benefit of 3% in the most favorable molecular scenario).

At low SNP densities, the genetic diversity maintained using genealogical coancestry for optimization was higher than that maintained using molecular coancestry.
