The given statistics indicate the comparison of the genome of the various organisms. Genome can be defined as the complete set of the genetic material (chromosomes/genes) present in the cell of an organism, or, the haploid set of the chromosomes which are present in an organism's gamete cell. Since, the given statistics are comparing the percentage of the genetic material which is similar among different organisms, the blank can be filled with 'genome'.
