A chromosomal translocation between two chromosomes rearrang

A chromosomal translocation between two chromosomes rearranges a standard karyotype of AB*CDEF & MN*OPQ to the translocated AB*OPQ & MN*CDEF (* indicates a centromere). Diagram how these chromosomes would pair in meiosis in an individual heterozygous for the translocation. What are the genotypes of the gametes that would be produced by adjacent and alternate segregation?

Solution

Gametes produced by adjacent and alternate segregations as follow:

During alternate segregation gametes may contain normal and translocated segments. AB*CDEF & MN*OPQ and AB*OPQ & MN*CDEF.

During adjacent segrgation gametes may contain one normal and one translocation chromosome, resulting in duplication of some genes and deficiency for others. AB*CDEF &MN*CDEF. and AB*OPQ & MN*OPQ
