We develop an extension to the Lander-Waterman theory for
characterizing gaps in bacterial artificial chromosome fingerprint mapping and shotgun sequencing projects. It supports a larger set of
descriptive statistics and is applicable to a wider range of project
parameters. We show that previous assertions regarding inconsistency of
the Lander-Waterman theory at higher coverages are incorrect and that
another well-known but ostensibly different model is in fact the same.
The apparent paradox of infinite island lengths is resolved. Several
applications are shown, including evolution of the probability density
function, calculation of closure probabilities, and development of a
probabilistic method for computing stopping points in bacterial
artificial chromosome shotgun sequencing.
