Every chromosome in one set has a matching partner in the other set that has the same length of DNA and the same genes. Cells that contain two sets of chromosomes are said to be diploid.

Gametes are haploid cells, and each cell carries only one copy of each chromosome. These reproductive cells are produced through a type of cell division called meiosis. During meiosis, a diploid ...

The nuclear genomes of most higher eukaryotic organisms are diploid and are characterized ... Gametes that result from meiosis are haploid and carry only a single allele (in this example, alleles ...

During fertilisation the haploid nucleus of a sperm cell and the haploid nucleus of an egg cell fuse together to form a diploid zygote.
