Final answer:
Robertsonian Translocation is the basis of an inheritable form of chromosomal translocation, which occurs when two nonhomologous chromosomes break and fuse together, potentially leading to genetic disorders or diseases.
Step-by-step explanation:
The basis of an inheritable form of chromosomal translocation is Robertsonian Translocation. This type of translocation occurs when two nonhomologous chromosomes break at their centromeres and the long arms fuse together, creating a single, large chromosome. This can result in the transfer of genetic material between chromosomes, leading to potential genetic disorders or diseases.
