Triploid pregnancy–Clinical implications
Clinical Genetics, 2021Abstract Triploidy is a life‐limiting genetic aberration resulting from an extra haploid set of chromosomes of paternal (diandric triploidy) or maternal origin (digynic triploidy). Triploidy affects around 1%–2% of all conceptions. The majority of cases is miscarried at early developmental stages. In consequence of genomic imprinting,

Summarythe data using a maximum‐likelihood method was that 66.4 yo of the triploids were the result of dispermy, 23.6 % the result of fertilization of a haploid ovum by a diploid sperm formed by failure of the first meiotic division in the male and 10 % the result of a diploid egg formed by failure of the first maternal meiotic division.

Approximately 60% of all human spontaneous abortions during the first trimester of pregnancy are associated with chromosomal aberrations of the conceptus. Nearly 20% of these karyotypes are triploid, 1,2 ie, 66 autosomes and three sex chromosomes. Hence, triploidy is one of the most frequent chromosome aberrations in human abortuses.

Diploid and triploid offspring of triploid agamosporous fernDryopteris pacifica
The Botanical Magazine Tokyo, 1992A cytological and reproductive study of the diploid and triploid agamosporousDryopteris pacifica was made to elucidate the origin of its infraspecific cytotypes. Some triploids produced 16 spore mother cells (SMCs) sometimes with n=41II+41I chromosomes, in addition to eight SMCs with n=123II, in each sporangium.

Triploidy has generally been considered to be an evolutionary dead end due to problems of chromosomal pairing and segregation during meiosis. Thus, the formation of tetraploids and diploids from triploid types is a rare phenomenon. In the present study, we demonstrated that inbreeding of the triploid planarian Dugesia ryukyuensis resulted in both ...
