Final answer:
GPS can reveal population-specific traits that GWAS cannot.
Step-by-step explanation:
GPS provides information about population-specific traits that GWAS cannot reveal. GPS analyzes the genetic variation present in different populations and can identify specific alleles that are associated with certain traits in those populations. This helps in understanding how traits are distributed across different populations and how genetic variations contribute to phenotypic expressions. GPS, which refers to Genomic Prediction of Selection, can reveal information about allele-trait associations that GWAS (Genome-Wide Association Studies) cannot. Specifically, GPS can provide insights into population-specific traits, which is how selective forces change the allele frequencies in a population over time. GWAS typically focuses on individual genetic variations and their associations with traits rather than how these variations and traits manifest and shift across entire populations. In contrast, GPS can illustrate the broader context of these variations within a population, as well as reflect upon the allele frequencies and their impact on the population's overall genetic makeup. Moreover, GPS has the ability to assess the genetic basis of traits within populations and whether these traits have a genetic underpinning. GPS can also help to understand the degree of inbreeding in a population, which can have significant implications for the genetic structure and trait expressions across the population. It's essential to note that the observable traits expressed by an organism are described as its phenotype, while the genetic codes for these traits are known as alleles.
