What is a diploid zygote?

Explanation:
A diploid zygote is the fertilized egg, the first cell of a new individual. It forms when a sperm and an egg fuse, bringing together two complete chromosome sets—one from each parent. In humans, each gamete has 23 chromosomes, so their union yields 46 chromosomes in the zygote, two copies of each chromosome. This two-set state is what “diploid” means. The zygote is different from an unfertilized gamete, which would have only one chromosome set, and from a cell with more than 46 chromosomes, which would be abnormal for a human. Hence, the product of fertilization containing 46 chromosomes best describes a diploid zygote.
