- g. 1 (G1) in the somatic cell cycle, the g. that follows mitosis and is followed by synthesis in preparation for the next cycle.

- g. 2 (G2) in the somatic cell cycle, a pause between completion of synthesis and the onset of cell division.

- air-bone g. the difference between the threshold for hearing by bone conduction and by air conduction.

- anion g. the difference between the sum of the measured cations and anions in the plasma or serum calculated as follows: (Na + K) – (Cl + HCO₃) = < 20 mmol /L. Elevated values may occur in diabetic or lactic acid osis; normal or low values occur in bicarbonate-losing metabolic acidoses. SYN: cation-anion difference.

- auscultatory g. the period during which Korotkoff sounds indicating true systolic pressure fade away and reappear at a lower pressure point; responsible for errors made in recording falsely low systolic blood pressure, especially in hypertensive patients, of up to 25 mm Hg, and avoided by pumping the cuff 30 mm Hg beyond palpable systolic pressure. SYN: silent g..

- Bochdalek g. SYN: lumbocostal triangle of diaphragm.

- chromosomal g. a localized area of thinning in a chromatid which may simulate a complete break.

- DNA g. a localized loss of one of the two strands in the double helix of DNA.
