diploid. (dĭp′loid′) adj. Having two sets of chromosomes or double the haploid number of chromosomes in the germ cell, with one member of each chromosome pair derived from the ovum and one from the spermatazoon. The diploid number, 46 in humans, is the normal chromosome complement of an organism's somatic cells.
Hereof, what does diploid refer to?
The main difference between haploid and diploid cells is the number of chromosome sets found in the nucleus. Ploidy is the area of biology that refers to the number of chromosomes in a cell. Therefore, cells with two sets are diploid, and those with one set are haploid.
What is a diploid cell?
Gametes or germ cells are haploid cells (example: sperm and ova) containing only one set (or n) number of chromosomes and autosomal or somatic cells are diploid cells containing 2n number of chromosomes. The number of chromosomes (n) differs in different organisms.
What does diploid 2n mean?
Diploid cells have two homologous copies of each chromosome, usually one from the mother and one from the father. All or nearly all mammals are diploid organisms. Human diploid cells have 46 chromosomes (the somatic number, 2n) and human haploid gametes (egg and sperm) have 23 chromosomes (n).
