Question

The movement of a chromosome segment from one linkage group to another is called as

• A. Translocation
• B. Crossing over
• C. Inversion
• D. Duplication

Answer 1

The correct option is A Translocation

• A set of genes at different loci on the same chromosome tend to act as a single pair of genes in meiosis instead of undergoing independent assortment.
• The chromosome translocation is caused by the rearrangement of parts between nonhomologous chromosomes. Hence in translocation, there is a movement of a chromosome segment from one linkage group to another
  Hence, correct option is A.
