WebOct 15, 2024 · Completely sequencing genomes is expensive, and to save costs we often analyze new genomic data in the context of a reference genome. This approach distorts our image of the inferred genome, an effect which we describe as reference bias. To mitigate reference bias, I repurpose graphical models previously used in genome assembly and …
In the pangenome, we can identify three sets of genes: Core, Shell, and Cloud genome. The Core genome comprises the genes that are present in all genomes analyzed. To avoid dismissing families due to sequencing artifacts some authors consider the softcore (>95% occurrence). See more In the fields of molecular biology and genetics, a pan-genome (pangenome or supragenome) is the entire set of genes from all strains within a clade. More generally, it is the union of all the genomes of a See more Core Is the part of the pangenome that is shared by every genome in the tested set. Some authors have divided the core pangenome in hard core, those families of homologous genes that has at least one copy of the family … See more The pan-genome can be somewhat arbitrarily classified as open or closed based on the alpha value of the Heap law: $${\displaystyle N=kn^{-\alpha }}$$ • $${\displaystyle N}$$ Number of gene families. • $${\displaystyle n}$$ Number of genomes.
