A medical genetics team evaluates a family in which a child has developmental delay and a karyotype showing 46 chromosomes with a reciprocal translocation between chromosomes 14 and 21. The child's parent carries the same translocation but is phenotypically normal and has no net gain or loss of chromosomal material (balanced carrier). During meiosis in the carrier, the translocated chromosomes form a quadrivalent structure. Which prediction is most consistent with chromosomal segregation in this carrier?
