acrocentric
1.Y-chromosome is a middle-sized acrocentric.
2.The X chromosomes were all submeta-centric and the Y chromosomes were acrocentric in five breeds.
3.Among 31 pairs of autosomes, of which 13 pairs were met centric or submetacentric and 18 pairs acrocentric chromosomes, X chromosome was larger submetacentric chromosome and Y was the smallest acrocentric chromosome.
4.Analyses of Satellite Association Frequencies ou the Patients with Nasopharygeal Carcinoma in Lymphocytic Acrocentric Chromosomes
5.X chromosome was the second largest submetacentric chromosome and Y was the smallest acrocentric chromosome in 1 pair sex chromosome.
6.The result showed that all autosomes which have short arm were acrocentric, the X and Y chromosomes were submetacentric.
7.The frequencies of satellite associations in acrocentric chromosomes in patient group were significantly high than those in control group.
8.It is composed 17 pairs of acrocentric,4 pairs of large submetacentric,4 pairs ofs(?) m(?) centric,one pair of acrocentric sex chromosomes and 4 or 6 B—chromosomes,The result isdifferent from the early one of Makino.
9.The number of the chromosomes 2n＝60 in goat and Capra ibex, All of the chromosomes were acrocentric chromosomes.
10.The numbers of chromosome of the grasshoppers of 3 species are all 2n(♂)=17=16+XO,16 autosomes are composed of 6 nearly median centromeric chromosomes and 10 acrocentric chromosomes,The X sexchromosome is acrocentric one too.
