Karyotype in conventional staining of Trinomys albispinus (MN82935) collected at Fazenda Galileia (locality 45) showing 2n=60, FN=108, with 25 pairs of biarmed and four pairs of acrocentric chromosomes; male individual, X chromosome as a large biarmed, and Y a small acrocentric chromosome.
In all taxa, karyotype has subtelocentric and acrocentric chromosome.
A heteromorphic autosomal pair was recorded in two specimens, consisting of a subtelocentric and an acrocentric chromosome (NFa = 67, Arslan & Zima 2015b).
Our findings conclusively argue that as well, where Robertsonian translocation between chromosome 21 and another acrocentric chromosome have been found in 16 children, while in only one child there was present reciprocal translocation between chromosomes 8 and 21.
In cytotype C2, silver staining revealed only one positive signal in a single ehromosome of the pair 1 whereas FISH with the 18S rDNA probe hybridized in two different chromosomes: one coincident with the Ag-NOR (pair 1) and other in one acrocentric chromosome, suggesting the occurrence of a peri-centric inversion.
The neo-X and neo-Y are the result of a centric fusion involving the former X acrocentric chromosome with an A1 chromosome of the acrocentric autosome pair A1A2 of the standard karyotype.
Approximately 500 species of entelegyne spiders, representing nearly 30 families, have a diploid number varying between 2n = 14 and 2n = 52, a predominantly acrocentric chromosome morphology, and a SDCS of the [X.
One plant contained 39 normal chromosomes plus one acrocentric chromosome (Fig.
11] cluster supported its use as an appropriate marker for investigating the introgression pattern of the centromeric region of an acrocentric chromosome.
A heteromorphic autosomal pair, consisting of a subtelocentric and an acrocentric chromosome (NFa = 69) was recorded in two specimens (Arslan & Zima, in press).
Considering that chromosome 13 is the largest acrocentric chromosome with the lowest gene density among all human chromosomes (17), its stability may differ from those of chromosomes 18 and 21.
Hypostomus strigaticeps (Figure 4b) showed multiple NORs due to markings found in the short arms on the subtelocentric chromosome pairs 10, 14 and 18, and in the acrocentric chromosome pair 29.
