If an individual is heterozygous for this translocation, the consequence in meiosis will be as follows:

A) Segregation results in a + c in one Gametes and b + d in another gametes, have duplication and deficiency so unable to produce viable offspring

B) Segregation results in a + b in one Gametes and c + d in another gametes, have normal chromosome so all viable offspring produced

C) Segregation results in a + d in one Gametes with normal chromosome and b + c in another gametes contains translocation arrangement, all viable offspring produced

D) Segregation results in a + d in one Gametes with normal chromosome, will produced viable offspring while b + c in another gametes contains translocation arrangement, will produce non viable offspring.
