10 April 2024Genomic prediction is a powerful statistical technique that uses genetic markers, typically single nucleotide polymorphisms (SNPs), to predict the genetic merit or breeding value of an individual. By analysing the relationship between an individual's genotype and its observed phenotype, genomic prediction models can estimate the additive genetic effects associated with different regions of the genome. This information can then be used to predict the genetic potential of animals or plants that have not yet been phenotyped, enabling more accurate selection decisions in breeding programmes.
Benefits of Genomic Prediction
Drawbacks of Genomic Prediction
Why Pedigree-Based Approaches Still Matter
While genomic prediction offers many advantages, pedigree-based selection methods remain an important component of modern breeding programmes. Pedigree information can provide valuable insights into the underlying genetic relationships and inheritance patterns within a population, which can complement the predictive power of genomic models.
Moreover, for some traits or species, pedigree-based approaches may still outperform genomic prediction, especially when the underlying genetic architecture is simple or the reference population is limited in size or diversity.
Embracing the Power of Genomic Prediction
Despite the potential drawbacks, the promise of genomic prediction is undeniable. By leveraging the power of high-throughput genotyping and advanced statistical models, breeders can make more informed decisions, accelerate genetic progress, and unlock new opportunities for genetic improvement.
