A number of types of life cycle are distinguishable, depending on the relative importance of the haploid and diploid condition of the chromosomes. A haploid organism contains a single set of chromosomes; whereas a diploid one has two sets, one set being inherited from each parent. The reduction from the diploid to the haploid number is carried out by a type of nuclear division called meiosis.
