WebCandidate genes were defined as annotated genes within 315 kb either side of a QTN, based on the LD decay of the chickpea reference set reported by Varshney et al. (2024). The candidate genes were verified for their function based on the literature reporting roles associated with plant-pathogen interactions. WebAllele frequency. Allele frequency, or gene frequency, is the relative frequency of an allele (variant of a gene) at a particular locus in a population, expressed as a fraction or percentage. [1] Specifically, it is the fraction of all chromosomes in the population that carry that allele over the total population or sample size.
