Genomic selection: A paradigm shift in animal breeding

Selection from Animal Breeding

Genomic selection - Revolutionary breeding practice in

With more and more Single Nucleotide Polymorphisms (SNPs) being identified throughout the genome, some of those SNPs will be found to be located within candidate genes, allowing the researchers to use the candidate gene approach on a genomewide scale. SNPs have some drawbacks but when compared to other markers they are more efficient and SNP consortium is growing to meet the requirements of gen...

Breeding and Genetics: Genomic Selection Methods II

Computer mating programs have helped breeders minimize pedigree inbreeding and avoid recessive defects by mating animals with parents that have fewer common ancestors. With genomic selection, breed associations, AI organizations, and on-farm software providers could use new programs to minimize genomic inbreeding by comparing genotypes of potential mates. Relationships could be computed between...

Does genomic selection have a future in plant breeding?

Plant breeding largely depends on phenotypic selection in plots and only for some, often disease-resistance-related traits, uses genetic markers. The more recently developed concept of genomic selection, using a black box approach with no need of prior knowledge about the effect or function of individual markers, has also been proposed as a great opportunity for plant breeding. Several empirica...
