The structure of an interchange chain of four chromosomes in Reticulitermes lucifugus (Isoptera: Rhinotermitidae)

All the male first meiotic divisions from three new Italian colonies of R. lucifugus are characterized by the presence of an interchange chain multiple of IV (2n = 19 II + CIV). C-banding of male meiocytes demonstrates that this chain has two terminal acrocentrics, located at each end of the multipl...

Description
Summary:All the male first meiotic divisions from three new Italian colonies of R. lucifugus are characterized by the presence of an interchange chain multiple of IV (2n = 19 II + CIV). C-banding of male meiocytes demonstrates that this chain has two terminal acrocentrics, located at each end of the multiple. This may explain why rings-of-four multiples never form.
