Which of the following is an example of a translocation? a chromosome containing the mutant sickle cell allele Two chromosomes have experienced breaks at their terminal ends (e.g., chromosome 6 and 18), and during the rejoining process, the ends get switched. The end of chromosome 6 becomes attached to chromosome 15 and vice verse an occurrence of nondisjunction at meiosis I an occurrence of nondisjunction at meiosis

It is of 2 types which are reciprocal and non-reciprocal translocation. reciprocal one show normal phenotype as compare to the other one, so option second is most appropriate example of chromosomal translocation.
