Exempel på hur man kan använda TRIPLOID i en mening

• Galax urceolata can occur at multiple ploidy levels, an individual may be a diploid (2x), triploid (3x), or autotetraploid (4x) (autopolyploid).
• These polyploid species produce seeds that are often parthenogenetic triploid or diploids, lack vigour and seldom grow to mature plants.
• On the other hand, a partial mole occurs when a normal egg is fertilized by one or two sperm, which then reduplicates itself, resulting in genotypes of 69,XXY (triploid) or 92,XXXY (tetraploid).
• Backcrossing with citron has produced a distinct group of triploid limes that are also of commercial value to a limited degree, the seedy Tanepeo, Coppenrath, Ambilobe and Mohtasseb lime varieties as well as the Madagascar lemon.
• Emphasizing the importance of re-establishing a healthy population of native trout in the area, sterile brook trout (triploid) and other sterile trout species, such as tiger and splake trout, were introduced to increase fishing opportunities.
• Jonagold is triploid, with sterile pollen, and as such, requires a second type of apple for pollen and is incapable of pollenizing other cultivars.
• Gravenstein (Danish: Gråsten, meaning "graystone", after Gråsten Palace) is a triploid apple cultivar that originated in the 17th century or earlier.
• Other cultivated potato species may be diploid (2n = 2x = 24), triploid (2n = 3x = 36), tetraploid (2n = 4x = 48), or pentaploid (2n = 5x = 60).
• This then produced a diploid unisexual, which backcrossed to inornata and produced triploid uniparens.
• The saffron crocus is now a triploid that is "self-incompatible" and male sterile; it undergoes aberrant meiosis and is hence incapable of independent sexual reproduction—all propagation is by vegetative multiplication via manual "divide-and-set" of a starter clone or by interspecific hybridisation.
• The haploid sperm and haploid egg fuse to form a diploid zygote, the process being called syngamy, while the other sperm and the diploid central cell fuse to form a triploid primary endosperm cell (triple fusion).
• Both diploid and triploid forms occur in the wild, but most cultivated plants are triploids which rarely produce seeds and primarily reproduce vegetatively by stolons.
• Different from nucellar embryony, double fertilization occurs via the syngamy of sperm and egg cells, producing a triploid endosperm and a diploid zygotic embryo.
• The diploid has 14 chromosomes (2n = 14), but there are triploid, tetraploid, hexaploid and octoploid "races" with 21, 28, 42 and 56 chromosomes, respectively.
• The FHIA-01 Goldfinger banana is a tetraploid (AAAB) hybrid of the cultivar Musa acuminata × balbisiana (AAB) 'Prata-anã' (a naturally occurring triploid clone from Brazil), and the cultivar SH-3142.
• Mosaicism in somatic triploid specimens of the Bufo viridis complex in the Karakoram with examination of calls, morphology and taxonomic conclusions.
• Some individuals of this species are diploid and reproduce sexually, while some are triploid or tetraploid and reproduce by apogamy (growth of a plant from a gamete without fertilization).
• In order to combat the invasive tendencies of Hypericum androsaemum, triploid clones of plants with desirable characteristics have been developed by several herbariums.
• "A new all-female triploid species of gecko and karyological data on the bisexual Hemidactylus frenatus from Vietnam".
• The Appalachian hybrid complex in Asplenium is a polyploid complex composed of three diploid species, three allotetraploid species formed by hybridisation and chromosome doubling from the former, and assorted diploid, triploid and tetraploid hybrids between the six species.
