The haploid number is the number of chromosomes in a gamete of an individual. This is distinct from the monoploid number which is the number of unique chromosomes in a single complete set.
As stated supra note 1, each parent donates a haploid number of chromosomes to the offspring, giving it a diploid number. In donating a haploid number of chromosomes, each parent donates one allele to the offspring. See Brian R.
A chromosome number that is not an exact multiple of the haploid number. Usually refers to an absence (monosomy) or an extra copy (trisomy) of a single chromosome.

In meiosis, the chromosome number is reduced from the diploid to the haploid number.
In fertilization, the nuclei of two gametes fuse, raising the chromosome number from haploid to diploid.
haploid Cells that contain only one member of each homologous pair of chromosomes (haploid number = n). At fertilization, two haploid gametes fuse to form a single cell with a diploid number of chromosomes.

A giant chromosome produced by an endomitotic process in which, following synapsis of the two homologues, multiple rounds of replication produce chromatids that remain synapsed together in a haploid number of chromosomes.

haploid The reduced, or N, number of chromosomes, typical of gametes, as opposed to the diploid, or 2N, number found in somatic cells. In certain groups, mature organisms may have a haploid number of chromosomes.
Gametes being haploid are essential particularly during fertilization. The union of two sex cells, each with only haploid number of chromosomes, results in a diploid zygote.
