Verified step by step guidance

Understand the concept of reciprocal translocation, which involves the exchange of segments between two non-homologous chromosomes.

Recognize that adjacent-2 segregation occurs during meiosis in individuals heterozygous for a translocation, leading to the separation of homologous centromeres.

Identify the chromosomes involved in the translocation: A B • C D E F G and J K • L M N O P, and A B • C D N O P and J K • L M E F G.

Determine the outcome of adjacent-2 segregation, where non-homologous centromeres segregate together, resulting in gametes receiving chromosomes A B • C D N O P and A B • C D E F G.

Conclude that adjacent-2 segregation results in gametes with the combinations A B • C D N O P and A B • C D E F G, as non-homologous centromeres segregate together.
