The following are some of the gene count estimates of human chromosome 18. Because researchers use different approaches to genome annotation their predictions of the number of genes on each chromosome varies (for technical details, see gene prediction). Among various projects, the collaborative consensus coding sequence project (CCDS) takes an extremely conservative strategy. So CCDS's gene number prediction represents a lower bound on the tota… WebApr 5, 2024 · Chromosome 18 has about 76 million nucleotides. Chromosome 19 has nearly 64 million nucleotides. ...
