diploid

 [dip´loid]
1. having a pair of each chromosome characteristic of a species (2n or, in man, 46).
2. a diploid individual or cell.

dip·loid

(dip'loyd),
Denoting the state of a cell containing two haploid sets derived from the father and from the mother respectively; the normal chromosome complement of somatic cells (in humans, 46 chromosomes).
[diplo- + G. eidos resemblance]

diploid

/dip·loid/ (dip´loid)
1. having two sets of chromosomes, as normally found in the somatic cells; in humans, the diploid number is 46.
2. an individual or cell having two full sets of homologous chromosomes.

diploid

(dĭp′loid′)
adj.
1. Double or twofold.
2. Genetics Having a pair of each type of chromosome, so that the basic chromosome number is doubled: diploid somatic cells.
n. Genetics
A cell, organism, or group of organisms having a diploid number of chromosomes.

diploid (2n)

[dip′loid]
Etymology: Gk, diploos + eidos, form
having two complete sets of homologous chromosomes, such as are normally found in somatic cells and primordial germ cells before maturation. In humans the normal diploid number is 46. Also called diploidic. Compare haploid, tetraploid, triploid.

diploid

adjective Referring to diploidy, see there. noun Having 2 haploid sets of chromosomes, one from an egg, one from sperm

dip·loid

(dip'loyd)
Denoting the state of a cell containing two haploid sets derived from the father and from the mother respectively; the normal chromosome complement of somatic cells (in humans, 46 chromosomes).
[diplo- + G. eidos resemblance]

diploid

Having an identical (homologous) pair of chromosomes for each characteristic except sex. This is the normal state of most body cells. Eggs and sperms, however, have only a single set of half the number of chromosomes, and are said to be haploid. Red blood cells have no chromosomes.

diploid

  1. (of a cell nucleus) containing two of each type of chromosome in homologous pairs and formed as a result of sexual reproduction.
  2. an organism in which the main life stage has cell nuclei with two of each type of chromosome, written as 2n. Diploid stages occur in all EUKARYOTES apart from certain fungi, and allow a greater degree of genetic variability in individuals than the HAPLOID (2) state (n).

diploid

stage within sex cell division when the gamete contains twice the normal number of chromosomes, i.e. 48 pairs rather than the normal 24 pairs

diploid

1. having a pair of each chromosome characteristic of a species, i.e. genomes in which chromosomes occur in pairs.
2. a diploid individual or cell.
