Tetraploid stocks of Caenorhabditis elegans var. Bristol carrying autosomal and X-linked markers have been produced.

The former are basically 4A;4X--four sets of autosomes and four sex chromosomes--and the latter are 4A;3X. Males are 4A;2X. (Diploid hermaphrodites are 2A;2X; males are 2A;1X.) Triploids were produced by crossing tetraploid hermaphrodites… CONTINUE READING
