Why does an embryo with a balanced translocation have the same chance for normal development that an embryo with a normal karyotype has?

A. The translocation stimulates DNA repair mechanisms to correct the problem before commitment occurs.
B. The embryo's somatic cells are unaffected, expressing a normal karyotype; only germline cells express the translocation.
C. Although the location of the genetic material is abnormal with a balanced translocation, there are no missing or extra alleles.
D. When a zygote with a balanced translocation reaches the embryo stage without a spontaneous abortion, the risk for abnormal development decreases.


Answer: C. Although the location of the genetic material is abnormal with a balanced translocation, there are no missing or extra alleles.
