Question

Translocation is a type of chromosomal aberration where

• A. Parts of chromosome is exchanged between homologous chromosomes.
• B. A part of one chromosome is exchanged between non-homologous counterpart.
• C. A part of one chromosome is shifted to its homologous counterpart.
• D. A part of one chromosome is shifted to another part of the same chromosome.

Answer 1

The correct option is B A part of one chromosome is exchanged between non-homologous counterpart.

The process of translocation is a kind of rearrangement in which block of genes from one chromosome are transferred to other non-homologous chromosome. Breaks in chromosomes are followed by union in ways different from the normal one.

So, the correct answer is 'A part of one chromosome is exchanged between non-homologous counterpart'.
