Comparative karyotype analysis in diploid and triploid Dolichoplana carvalhoi (Tricladida, Terricola, Rhynchodemidae) from Brazil

open access: yesGenetics and Molecular Biology, 2007
In this work, we present cytogenetic data for the land planarian Dolichoplana carvalhoi. Two different karyotypes, one diploid (2n = 2x = 14 chromosomes) and one triploid (2n = 3x = 21 chromosomes), corresponding to two morphological body patterns, are ...

Prenatal diagnosis of a partial dup (16p) due to a rare recombinant resulting from a paternal intrachromosomal insertion [PDF]

open access: yes, 2011
Poster: 10.P7Chromosomal rearrangements involving three break-points are relatively rare, about 1/5,000 live births. When a chromosomal segment is moved from one part of a chromosome into another part of the same chromosome, it is considered an ...

Seasonal Emergence Patterns of Black Flies (Diptera: Simuliidae) in Northwestern Pennsylvania [PDF]

open access: yes, 2017
A two-year emergence trap study of black flies at four sites in northwestern Pennsylvania yielded 1%3 individuals of nine species. The collections included Prosimulium mixtum, P. jU5cum, Stegapterna mutata, Simulium aureum, S.

Prenatal Cell‐Free DNA Screening With Fetal Enrichment Enables Sampling From 8 Weeks of Gestational Age

open access: yesClinical Genetics, Volume 109, Issue 1, Page 68-76, January 2026.
Fetal fraction (FF) estimates for 170 male pregnancies sampled between 7w0d and 9w6d of GA as a function of gestational age at blood draw without (blue triangles) and with fetal enrichment (red dots). Regression lines are shown (gray 95% CI). Besides, there is a closer look at samples below 4% FF.

Mixoploidy combined with aneuploidy in a 13 year-old patient with severe multiple congenital abnormalities and intellectual disability [PDF]

open access: yes, 2018
Structural pathology and outcome were studied in 170 chromosomally abnormal fetuses. Numerical chromosomal abnormalities were established in 158 (93 per cent) cases, of which 110 (71 per cent) represented trisomies, 30 (18 per cent) Turner syndrome, and ...

Evidence for viable and stable triploid Trypanosoma congolense parasites

open access: yesParasites & Vectors, 2017
Background Recent whole genome sequencing (WGS) analysis identified a viable triploid strain of Trypanosoma congolense. This triploid strain BANANCL2 was a clone of the field isolate BANAN/83/CRTRA/64 that was collected from cattle in Burkina Faso in ...

Investigating the frequency of triploid Atlantic salmon in wild Norwegian and Russian populations

open access: yesBMC Genetics, 2018
Background Fish may display variations in ploidy, including three sets of chromosomes, known as triploidy. A recent study revealed a frequency of ~ 2% spontaneous (i.e., non-intentional) triploidy in domesticated Atlantic salmon produced in Norwegian ...

Allelic segregation and independent assortment in T. brucei crosses: proof that the genetic system is Mendelian and involves meiosis [PDF]

open access: yes, 2005
The genetic system on Trypanosoma brucei has been analysed by generating large numbers of independent progeny clones from two crosses, one between two cloned isolates of Trypanosoma brucei brucei and one between cloned isolates of T. b.

Gene expression response under thermal stress in two Hawaiian corals is dominated by ploidy and genotype

open access: yesEcology and Evolution
Transcriptome data are frequently used to investigate coral bleaching; however, the factors controlling gene expression in natural populations of these species are poorly understood.

Triploidy in zebrafish larvae: Effects on gene expression, cell size and cell number, growth, development and swimming performance.

open access: yesPLoS ONE, 2020
There is renewed interest in the regulation and consequences of cell size adaptations in studies on understanding the ecophysiology of ectotherms. Here we test if induction of triploidy, which increases cell size in zebrafish (Danio rerio), makes for a ...
