Definition of diploid :
The state of having each chromosome in two copies per nucleus or cell. A cell or an organism having two chromosome sets or twice the haploid number, or an individual having two chromosome sets in each of its cells. This can be seen by the presence of 2 of each type of chromosome in a cell nucleus at interphase. In most cells this is the typical number of chromosomes.
In humans this number is 46. It is naturally twice the haploid number of 23 chromosomes contained in human eggs (ova) and sperm.
