Uncoordinated and sterile with cell proliferation defects in germ and somatic cells. Hermaphrodite gonads have fewer cells with 13% of homozygotes having only one gonad arm. Most hermaphrodite mutants contain sperm but only 20% contain oocytes that develop as far as diakinesis and those that develop exhibit abnormal karyotypes. Mutant adults contain significantly fewer D neurons and seam cells than wild type. No poly-guanine tract deletions but double mutants of chl-1 and dog-1 display increased deletion frequency when compared to dog-1 mutants.1 Publication

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1.
