Verified step by step guidance

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

Recognize that in a heterozygous individual for a reciprocal translocation, chromosomes can segregate in different ways during meiosis, leading to different combinations in gametes.

Identify the two types of segregation: alternate and adjacent. In alternate segregation, non-homologous centromeres go to opposite poles, resulting in balanced gametes.

Examine the given chromosomes: 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 that after alternative segregation, the gametes receive the chromosomes A B • C D N O P and J K • L M E F G, as these represent a balanced set of genetic material.
