D)Pericentric inversion
E)Reciprocal translocation

Question

Quizplus · Accepted Answer

Loops form during chromosome pairing in prophase I of meiosis when there are structural differences between homologous chromosomes, such as deletions, duplications, and inversions, which require the chromosomes to loop out to align properly. Reciprocal translocation, however, involves the exchange of segments between non-homologous chromosomes and does not necessitate the formation of loops for alignment during meiosis.
