Diploid
Diploid is a cell or organism that has paired chromosomes, one from each parent. In humans, cells other than human sex cells, are diploid and have 23 pairs of chromosomes.
Diploid A full set of genetic material, consisting of paired chromosomes one chromosome from each parental set. Most animal cells except the gametes have a diploid set of chromosomes. The diploid human genome has 46 chromosomes. Compare haploid.
Diploid (2n) cells have two homologous copies of each chromosome, usually one from the mother and one from the father.
Diploid
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.
diploid life cycle -- Occurs when the only multicellular stage in an organism's life cycle is diploid.
Diploid
An organism which contains pairs of each chromosome.
Direct repeats
Two identical (or nearly identical) nucleotide sequences sometimes separated by a sequence of non-repeated DNA. For example, 3' TAGT . . . TAGT 5'
5' ATCA . . .
diploid - a cell that contains two of each type of chromosome, such as a human somatic cell.

Diploid (DIP-loyd) Having two sets of chromosomes, one inherited from each parent. All human cells except eggs and sperm are diploid and have 46 chromosomes, 23 from each parent.
diploid Cells that contain homologous chromosomes. The number of chromosomes in the cells is the diploid number and is equal to 2n (n is the number of homologous pairs).

Diploid number (2n): The full complement of chromosomes in a somatic cell (or a sex cell before meiosis). In humans, the diploid number is 46.
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 set for humans; 2n = 46

Diploid organisms naturally have a maximum of 2 alleles for each gene expressing a particular characteristic, one deriving from each parent.
diploid Having the somatic (double, or 2N) number of chromosomes or twice the number characteristic of a gamete of a given species.
Diploid organisms have two copies of each gene. When a mutation in one copy occurs the organism can have alternate alleles with different properties.
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.

Haploid and diploid are terms referring to the number of sets of chromosomes in a cell. Gregor Mendel determined his peas had two sets of alleles, one from each parent. Diploid organisms are those with two (di) sets.

There are diploid (2n=22); triploid (3n=33), and tetraploid (4n=44) watermelons. When the tetraploid plant (4n =44) undergoes meiosis, it makes gametes with a diploid number, of chromosomes (2n=22).
Plants exhibit life cycles that involve alternating generations of diploid forms, which contain paired chromosome sets in their cell nuclei, and haploid forms, which only possess a single set.
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.

When the chromosomes are visible, cells with two complete sets of chromosomes are called diploids (46 in a human). Most cells are diploid. Cells with only one set (23 in a human) are called haploid cells.
The process of two consecutive cell divisions in the diploid progenitors of sex cells. Meiosis results in four rather than two daughter cells, each with a haploid set of chromosomes.

The condition of a cell or of an organism that has additions or deletions of a small number of whole chromosomes from the expected balanced diploid number of chromosomes.
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.
