Question
A reciprocal translocation happened between chromosomes 1 and 2 in a wild species of strawberries. Below is a diagram of (unreplicated) chromosomes 1 and 2 for the translocated strain of strawberries. N1 and N2 indicate the normal chromosomes 1 and 2, respectively; T1 and T2 are their translocated counterparts.
Which chromosomes must segregate from one another at anaphase I to form viable meiotic products?
A) N1 and T1 separate from N2 and T2.
B) N2 and T1 separate from N1 and T2.
C) N1 and N2 separate from T1 and T2.
D) T1 separates from T2, N1, and N2.
E) N1 separates from N2, T1, and T2.
Explanation / Answer
The correct option is C) N1 and N2 separate from T1 and T2, because T1, and T2 has same gens as N1 and N2.
