Answer:
The exchange of chromosome segment between non-homologous chromosomes is called translocation.
It is of two types:
- Reciprocal translocation
There is an exchange of chromosome segments between two non- homologous chromosomes in reciprocal translocation.
- Non- reciprocal translocation
A part of chromosome is translocated from one non-homologous chromosomes to other so that one chromosome becomes deficient and another non-homologous chromosome gains the piece of chromosome and becomes long.
