Definition
English
:
Metacentric
chromosomes
produced during
MEIOSIS
or
MITOSIS
when the
CENTROMERE
splits transversely instead of longitudinally. The
chromosomes
produced by this abnormal division are one
chromosome
having the two long arms of the original
chromosome
, but no short arms, and the other
chromosome
consisting of the two short arms and no long arms. Each of these
isochromosomes
constitutes a simultaneous duplication and deletion.
