aP1P1M: Triploid diandric homozygous conceptus. P1P2M: Triploid diandric heterozygous conceptus.
bIn squared brackets are given the number of metaphases where the karyotype indicated were observed. The term “mos” is used where cells with two different karyotypes were observed, although we have not specifically analyzed whether this was caused by mosaicism or chimerism.
