Which process may result from the rearrangement of a translocated chromosome?

The rearrangement of a translocated chromosome can lead to potential loss of essential genes due to the way genes may be disrupted or inactivated during this process. When chromosomes are translocated, segments of DNA are moved from one location to another, often between non-homologous chromosomes. This reorganization can physically separate genes from their regulatory elements or even relocate them to a less favorable context in the genome.

In some cases, if a translocation leads to the fusion of two genes, it might create a new gene product, but essential genes can be deleted or rendered nonfunctional during this process. The disruption of critical genes can have significant effects on the organism's phenotype and viability, leading to developmental issues or diseases. This potential for losing essential genetic information or functionality is a direct consequence of the structural changes induced by translocations. Thus, option B accurately reflects the risk associated with chromosome rearrangement resulting from translocation.
