haploid

  1. (of a cell nucleus) containing one of each type of chromosome.
  2. a haploid organism in which the main life stage has cell nuclei with one of each type of chromosome, written as ‘n’. Such organisms (e.g. fungi, many algae) usually have a brief DIPLOID (2) phase (2n), returning to the haploid state via MEIOSIS. See ALTERNATION OF GENERATIONS.
