A) Deletion
B) Duplication
C) Inversion
D) Reciprocal translocation
Correct Answer: D
Solution :
Inversion involves a reverse order of genes in part of chromosomes. In figure, break occurs between A and E. Remain at the broken ends may lead to inversion of segment BCD into DCB. In deletion, a section of chromosome is lost. In duplication, a section of chromosome is duplicated. In reciprocal translocation an exchange of chromosome fragment occurs in between two non-homologous chromosomes.
