A)alternate
B)adjacent-1
C)adjacent-2
D)nondisjunction

Question

Quizplus · Accepted Answer

In alternate segregation, the translocated chromosomes segregate such that the normal and translocated homologous chromosomes separate during meiosis I. This results in gametes with balanced chromosome complements, which can result in the formation of a normal zygote. In adjacent-1 or adjacent-2 segregation, the translocated chromosomes segregate in a way that leads to gametes with unbalanced chromosome complements, and in nondisjunction, the chromosomes fail to segregate properly, also leading to gametes with unbalanced chromosome complements, which can result in abnormal zygotes or developmental problems.
