Ploidy (/ ˈ p l ɔɪ d i /) is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. Diploid cells undergo mitosis. As diploid means two set of chromosomes, haploid comprises of one set of chromosome. Identification of haploid/diploid cells by species-specific markers demonstrated that haploid cells were amplified only by oligonucleotides specific for H. huso male, which proved the paternal origin of the haploid cells. Usually, human somatic cells consist of two chromosome sets; each is inherited from one parent. … The most important distinction between diploid and haploid is the number of chromosome sets found in the nucleus.
