An apple variety with three sets of chromosomes which have sterile pollen; typically vigorous tree.
A state of 69 chromosomes, or three times the haploid number, most commonly caused by fertilisation of the egg with two sperm; the embryo that results can develop as far as a fetus, but is doomed to miscarry. The trophoblast of the placenta often undergoes partial changes of a hydatidiform mole. The noun form for this adjective is triploidy (the state of being triploid).
An organism with three basic (n) sets of chromosomes.
( Genet.). Having three chromosome sets; the individual so constituted. ( BCFT).
n. (Gr. triplus, triple) having or being a chromosome number three times the monoploid number.
A cell (or organism) having three copies of the haploid genome.
having three sets of chromosomes instead of the usual two
Describing a nucleus or cell that has three times (3n) the haploid number (n) of chromosomes
having three times the number of chromosomes characteristic of somatic cells.
of a cell or organism having three complete sets of chromosomes; "human triploid fetuses are usually spontaneously aborted"
A genetic term referring to non-reproducing (sterile) forms of grass carp induced by manipulating reproductive genes. Reproducing grass carp have two pairs of chromosomes and are termed diploid. Triploid fish have three sets of chromosomes.
An organism, or a cell type, with a chromosomal complement of three times the haploid number of chromosomes. A haploid cell (for example a pollen cell) contains a single set of chromosomes. An example of a triploid species is the cultivated banana.
having three of the basic sets of chromosomes in the nucleus.
A cell with three copies of each chromosome or an individual made up of such cells.
A cell or organism containing three times the haploid number of chromosomes.
Having three sets of chromosomes rather than the usual two. As a result, the pollen is sterile. Because triploids such as the Stayman Winesap lack viable pollen they aren't effective for pollenizing other apple trees. If a Stayman Winesap is planted, a pollen variety must be planted with it. A third appropriate apple variety must be planted to pollenize the second tree. .
A cell having three chromosome sets or an organism composed of such cells.
Having an extra set of chromosomes. Often causes gigantism and other genetic morphs.
