  • ↵Estimated assuming a genome size of 3000 Mb and the percentage of the total cytogenetic length represented by each chromosome (W. Nash, unpubl.).

  • ↵Values are underestimates due to gaps in map (e.g. B3, E1) or poor physical coverage (e.g. Y).

  • ↵Bears the selectable locus, thymidine kinase (TK).
