Sentence examples for exogenous population from inspiring English sources

The number of SNP in both studies was similar, and the simulated and real data set only changed in the similarity between the native and exogenous population.

The non-marker loci were used only for evaluation (not for management), as alleles originating from the native population were distinguishable from those originating from the exogenous population.

Table  4 shows the results of the performance of the de-introgression process when using genotypes of descendants of the exogenous population to recover the native genetic background.

Moreover, information on the descendants of the exogenous population instead of the actual exogenous individuals entering the native population can help identify the purest individuals to achieve a high level of recovery of the native genetic material.

Genome-wide information can be used to remove introgressed genetic material and to completely recover the native genetic background when the contribution of the exogenous population is limited to 30-40% and the number of generations of admixture is not too high (one to three generations).

Molecular coancestry between individuals in the current and exogenous populations as calculated above considered that genotypes were available for all exogenous individuals.

Genetic distances were useful when dealing with markers with several alleles, but only in cases for which allelic frequencies were sufficiently different between the native and exogenous populations.

Genome-wide information can be used to identify the purest individuals via the minimisation of molecular coancestry between individuals of the admixed and exogenous populations.

Hence, exclusive markers (i.e. having private alleles occurring only in native or exogenous populations) obtained good results even with few markers (5 10), and more markers were required when alleles were segregating in both native and exogenous populations at intermediate frequencies (i.e. more similar populations).

A matrix X, composed of x ij values is constructed for individuals in the current and exogenous populations and the matrix of genomic relationships between current (c) and exogenous (ex) individuals is calculated as: (2) A = X c X ' ex N mark where N mark is the total number of markers.

Native and exogenous populations included 100 individuals each (50 males and 50 females) and the genome of each individual was made up of 20 chromosomes, each one Morgan long and carrying two types of biallelic loci: 2500 markers and 25 000 non-marker loci.
