diploid cell
(dip-loyd) [Gk. di, double, two + ploion, vessel]
A cell containing two sets of chromosomes (2n), one set inherited from each parent.

Diploid cell. A cell which contains two copies of each chromosome. See Haploid cell.
Diploid cells (2N) have two complete sets of chromosomes. The body cells of animals are diploid.
Haploid cells have one complete set of chromosomes. In animals, gametes (sperm and eggs) are haploid.
Homologous Chromosomes ...
Diploid Cell (2N): From a preceding mitotic division, the Oogonium (Spermatogonium) enters meiosis with DIPLOID (2N) chromosomes but TETRAPLOID (4N) DNA. Chromosomes then duplicate to produce SISTER CHROMATIDS (or HOMOLOGOUS DYADS).
Diploid cells (meaning double in Greek) have two copies (homologs) of each chromosome (both sex- and non-sex determining chromosomes), usually one from the mother and one from the father.
A diploid cell missing a single chromosome. A cell or individual that is basically diploid but that has only one copy of one particular chromosome type and thus has chromosome number 2n - 1.

zygote Diploid cell produced by the fusion of an egg and sperm; fertilized egg cell.
zygotic meiosis. Meiosis that takes place within the first few divisions after zygote formation; thus all stages in the life cycle other than the zygote are haploid.
Mostly diploid cell formed by union of twogametes or reproductive cells. Ovum (female gamete) fertilized by a sperm (male gamete).

Gametogenesis is the process of forming gametes (by definition haploid, n) from diploid cells of the germ line.
In human beings females have two X chromosomes in diploid cells; males have an X and a Y chromosome. The sex chromosomes comprise the 23rd chromosome pair in a human karyotype. Compare autosome.

Each diploid cell in the human body features only one nucleolus, though immediately after cell division ten tiny nucleoli appear before they coalesce into a single, large nucleolus.

While the amount of DNA for a diploid cell is constant within a species, the differences can be great between species. Humans have 3.5 X 109 base pairs, Drosophila has 1.5 X 108, toads have 3.
In meiosis, a diploid cell divides to produce four haploid cells, each with half the original chromosome content. For this reason, meiosis is often called a "reduction division".
Mammalian genomic DNA (including that of humans) contains 6x109 base pairs of DNA per diploid cell.
Better yet, the wind blows the pollen to another conifer of the same species, and a cone (called the ovulate cone) catches the pollen. Again, the pollen and megaspore (receiving haploid cell) are haploid and combine to form a diploid cell.
primary oocyte
A diploid cell formed after a diploid oogonium underwent mitosis. The primary oocyte is arrested in Prophase of Meiosis I. It will complete meiosis to form a haploid primary oocyte and the haploid first polar body.
The process of meiosis essentially involves two cycles of division, involving a gamete mother cell (diploid cell) dividing and then dividing again to form 4 haploid cells.
Zygote: A fertilized egg. Or the diploid cell that results from the joining of two haploid gametes (sperm and egg) during sexual reproduction, that will cleave to form an embryo. See also fertilization, gamete.
Sex chromosome The X or Y chromosome in human beings that determines the sex of an individual. Females have two X chromosomes in diploid cells; males have an X and a Y chromosome.
Females have two X chromosomes in diploid cells; males have an X and a Y chromosome. The sex chromosomes comprise the 23rd chromosome pair in a karyotype. Compare autosome.
The X or Y chromosome in human beings that determines the sex of an individual. Females have two X chromosomes in diploid cells; males have an X and a Y chromosome. The sex chromosomes comprise the 23rd chromosome pair in a karyotype.
humans, every chromosome is paired, one inherited from the mother, the other inherited from the father. When an organism produces gametes, the gametes end up with only one of each chromosome per cell. Haploid gametes are produced from diploid cells ...
So the cells are synchronized and they fuse and make a diploid cell. Those hormones also arrest division in G1, so we called this point of control in yeast cells "start," because it was the point in whichcontrol occurred.
