Recombination may be said to differ from mutation in that it is usually a reciprocal
exchange of DNA sequences ( " genes ' ) that are themselves not altered .
However , crossing over is not always reciprocal , and it may occur within the
confines ...

In the heterozygous condition , a metacentric chromosome usually segregates
normally from the homologous acrocentrics with which it pairs , so the gametes
are usually euploid ( i . e . , have a complete haploid genome ) . GENE
