acrocentric

In the female, all except a pair of very large submetacentric chromosomes were found to be acrocentric.

Five pairs are acrocentric chromosomes and one pair is metacentric.

All chromosomes are acrocentric but the first pair of autosomes, which is submetacentric.

Robertsonian translocations have been seen involving all combinations of acrocentric chromosomes.

They can be connected in either metacentric, submetacentric, acrocentric or telocentric manner.

It has one pair of large submetacentric autosomes and 27 acrocentric autosomal pairs.

Its karotype is unique among that group, as it possesses two pairs of acrocentric macrochromosomes.

The normal mouse has 40 chromosomes which are all acrocentric with centromeres close to the terminus and almost invisible short arms.

The remaining autosomal pairs are smaller and acrocentric (with the shorter chromosome arm difficult to observe).

Both the X and Y chromosomes are acrocentric.

The W chromosomes are acrocentric too, as are the larger microchromosomes, the smaller ones probably being telocentric.

Except for the X chromosome, all chromosomes are acrocentric (with the short arm absent or virtually absent).

Of its chromosomes, 22 are metacentric, 26 are submetacentric, and none are acrocentric.

The X chromosome is the largest acrocentric, and the Y chromosome a medium-sized one.

This type of rearrangement involves two acrocentric chromosomes that fuse near the centromere region with loss of the short arms.

Thus, FN 2 x 2n, the difference depending on the number of chromosomes considered single-armed (acrocentric or telocentric) present.

A Robertsonian translocation results when the long arms of two acrocentric chromosomes fuse at the centromere and the two short arms are lost.

The two largest macrochromosome pairs are submetacentric, while all other chromosomes are acrocentric or (for the smallest microchromosomes) probably telocentric.

The X chromosome is either acrocentric, with a long and a short arm, or subtelocentric, with a long and a vestigial arm.

In some cases, a metacentric chromosome is formed by balanced translocation: the fusion of two acrocentric chromosomes to form one metacentric chromosome.

The Y chromosome is metacentric and the X chromosome is variable, ranging from nearly metacentric to acrocentric in five specimens studied.

The domestic horse genome includes one metacentric chromosome that is homologous to two acrocentric chromosomes in the conspecific but undomesticated Przewalski's horse.

C-banding stains the constitutive heterochromatin, which usually lies near the centromere, and NOR staining highlights the satellites and stalks of acrocentric chromosomes.

Ten non homologous acrocentric chromosomes in one animal correspond to five metacentric chromosomes in the other; the other eight pairs of metacentrics are common to all forms.
