Genome Size


Genome sizes of organisms vary widely between and within different phylogenetic groups. Factors contributing to the genome sizes are duplication of a part or the whole of the genome, insertions, spread of repetitive elements and deletion of part or whole chromosomes.

Keywords: genome size; C‐value; chromosome number; minimal genome; synteny
