Verified step by step guidance

Understand the concept of reciprocal translocation: This occurs when two non-homologous chromosomes exchange segments, leading to a rearrangement of genetic material.

Learn about the different types of segregation patterns during meiosis in translocated chromosomes: Adjacent-1, Adjacent-2, and Alternative segregation.

Adjacent-1 segregation involves the separation of homologous centromeres, leading to gametes with duplications and deficiencies, which are typically inviable.

Adjacent-2 segregation involves the separation of non-homologous centromeres, also resulting in gametes with duplications and deficiencies, which are typically inviable.

Alternative segregation results in the separation of translocated chromosomes from their normal homologs, producing balanced gametes with no duplications or deficiencies, thus viable.
