1. The X chromosome is metacentric and the Y chromosome is acrocentric . 2. Robertsonian translocations have been seen involving all combinations of acrocentric chromosomes. 3. It has one pair of large Y chromosomes are the largest and smallest acrocentrics . 4. The X chromosome is a large acrocentric while the Y chromosome a minute one. 5. All chromosomes are acrocentric except for the first pair of autosomes, which are submetacentric. 6. It has eight metacentric chromosomes, four submetacentric to acrocentric , and two submetacentric chromosomes. 7. In the female, all except a pair of very large submetacentric chromosomes were found to be acrocentric . 8. The X chromosome is the largest of the acrocentric chromosomes, and the Y chromosome is medium-sized. 9. The species has 50 chromosomes ( 2n = 50 ), and it genome size is 3.58 acrocentric . 10. When described by Simons in 1988, size, acrocentric ( with the shorter chromosome arm difficult to observe ).
