Which of the following is correct statement Types of disjunction in a translocation heterozygote during meiosis I.
A) Centromeres 1 and 3 go to one pole and centromeres 2 and 4 go to the other pole, producing non fuctional gametes.
B) Centromeres 1 and 2 go to one pole and centromeres 3 and 4 go to the other pole, producing viable gametes.
C) Centromeres 2 and 3 go to one pole and centromeres 1 and 4 go to the other pole, producing euploid gametes.
