is a chromosomal abnormality caused by an additional haploid set of chromosomes.
In molluscs, the manipulation of the chromosomal set aiming triploidy
can be achieved by using physical or chemical shocks during meiosis I (PB 1), II (PB 2), or both (Colas & Dube 1998, Guo et al.
Amongst the most common of the chromosome abnormalities that continue during pregnancy are trisomy 21 (Down syndrome), trisomy 18 (Edward syndrome); trisomy 13, (Patau syndrome); Turner syndrome (typically inheritance of one X chromosome instead of two) and triploidy
(more than one set of chromosomes).
Currently, most NGS-based PGS technologies are limited in that they cannot detect all forms of triploidy
in an embryo.
Three weeks later it was discovered Emily had Triploidy
, a chromosomal disorder where babies have an added set of chromosomes.
Two laboratories (9, 10) have independently shown that these oocytes can be fertilized and therefore cause digynic triploidy
in the embryo.
Foetal infections such as cytomegalovirus, toxoplasmosis and chromosomal anomalies such as triploidy
and trisomy 13 and 18 also result in IUGR.
(4, 5, 13, 15, 17, 18) a chromosome 4 deletion, and multiple anomalies were reported in the abdominal cases (n=5; 83%).
The analysis of chromosomal aberrations was classified as numeric (autosomal trisomy -21, 18, 13, 17, 7-, monosomy, triploidy
, and sex CA), structural (inversion, deletion, de novo marker, Robertsonian translocation, reciprocal translocation, chromosomal variant), and single gene disorders (fragile X syndrome, maple syrup disease, spinal muscular atrophy, congenital adrenal hyperplasia, thalassemia).
is widely used to obtain faster growth in different oyster species (Nell, 2002) since produces sterility (Garnier-Gere et al.
Cherfas NB, Kozinsky O, Rothbard S, Hulata G (1990) Induced Diploid Gynogenesis and Triploidy
in Ornamental (Koi) Carp, Cyprinus carpio L.
They thought she had a condition called triploidy
, which means they are incompatible with life.
