(A) FISH images from blastomeres biopsied from day-3 embryos. The DNA is counterstained aqua, and colored spots represent the specific signals for chromosomes 13 (red), 16 (aqua), 18 (blue), 21 (green), and 22 (gold). (E1) Embryo 1 has a normal complement of the chromosomes tested. (E2) Embryo 2 has a normal complement of the chromosomes tested. (E3) Embryo 3 has an abnormal complement of the chromosomes tested because it has trisomy 13. (E4) Embryo 4 has an abnormal complement of all the chromosomes tested. (B) Ultrasonographic examination at 6 weeks and 5 days of gestation, showing two interuterine gestation sacs. D1 and D2 indicate the presence of two embryos within one sac.
