The effect of explosive population growth on the numbers and counts of newly arising variants, under three population scenarios: explosive population growth (blue), equivalent exponential growth (red), and in a constant population (green). (A) Variants arising (solid lines) and surviving (dashed lines) as a function of time of origin. (B) Expected numbers of copies of each surviving variant as a function of time of origin. (C) The age probability distributions of variants currently present in 10 (solid lines) and 120 (dashed lines) copies.
