Dizygotic twins twins arising by the fertilisation of two eggs by two sperm. therefore no more identical than normal sibs.
Dicentric chromosome: One chromosome having two centromeres.
Dikaryotic: A cell that contains two separate haploid nuclei (n+n) which is different from being haploid (n) or diploid (2n). Naturally seen in fungal heterokaryons.

In rare cases in humans, neocentromeres can form at new sites on the chromosome. This must be coupled with the inactivation of the previous centromere since chromosomes with two functional centromeres (dicentric chromosomes) will result in ...
