Parental origin of the genome and karyotype in seven of 278 diploid androgenetic conceptuses in which aneuploidy was observed.

^aP1P1: Diploid androgenetic homozygous conceptus. P1P2: Diploid androgenetic heterozygous conceptus. P1P2/PM: By karyotyping, the conceptus was classified as diploid, in three loci three alleles were observed, of which only one was identical to a maternal allele, and in all loci the height of the peaks indicated that two diploid cell lines were present, one androgenetic and one biparental¹⁰.

^bIn squared brackets are given the number of metaphases where the karyotype indicated was 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.
