Triploid syndrome, also called triploidy, is a chromosomal disorder in which a fetus has three copies of every chromosome instead of the normal two. If this occurs in only some cells, it is called mosaic triploidy and is less severe. Most embryos with triploidy miscarry early in development.
Diploid-triploid mosaicism is a human chromosome disorder.Individuals with diploid-triploid syndrome have some cells with three copies of each chromosome for a total of 69 chromosomes (called triploid cells) and some cells with the usual 2 copies of each chromosome for a total of 46 chromosomes (called diploid cells).
triploid (three sets; 3x), for example sterile saffron crocus, or seedless watermelons, also common in the phylum Tardigrada [11] tetraploid (four sets; 4 x ), for example, Plains viscacha rat , Salmonidae fish, [ 12 ] the cotton Gossypium hirsutum [ 13 ]

Triploid organisms, for instance, are usually sterile. Because of this, triploidy is commonly exploited in agriculture to produce seedless fruit such as bananas and watermelons. If the fertilization of human gametes results in three sets of chromosomes, the condition is called triploid syndrome. [citation needed]

Confined placental mosaicism (CPM) represents a discrepancy between the chromosomal makeup of the cells in the placenta and the cells in the fetus. CPM was first described by Kalousek and Dill in 1983. [1]
The result of digyny is a triploid zygote. In humans, both gametes (ovum and sperm) are normally haploid and give rise to a diploid zygote. [1] Digyny results in gestational abnormalities in humans, including an abnormally small placenta and a very growth-restricted fetus. As a result, the majority of triploid pregnancies are spontaneously aborted.
