The type of chromosome abnormality that yields a long chromosome consisting of most of two acrocentric chromosomes is a(n)
A)Robertsonian translocation.
B)pericentric inversion.
C)paracentric inverson.
D)reciprocal translocation.

Question

Quizplus · Accepted Answer

A Robertsonian translocation involves the fusion of two acrocentric chromosomes into one long chromosome. In contrast, pericentric and paracentric inversions do not involve the fusion of two chromosomes. Reciprocal translocation involves the exchange of genetic material between two non-homologous chromosomes.
