diploid
A cell with two sets of chromosomes is diploid , referred to as 2n , where n is the number of sets of chromosomes. Most of the cells in a human body are diploid. A cell with one set of chromosomes, such as a gamete, is haploid , referred to as n . Sex cells are haploid. When a haploid sperm n and a haploid egg n combine, a diploid zygote will be formed 2n . In short, when a diploid zygote is formed, half of the DNA comes from each parent.
