Chromosomal ploidy results of the embryos (A–F) from patient 2. Twelve embryos, A–L, were subjected to chromosomal analysis, and the chromosomal ploidy results of the embryos (G–L) were supplied in Supplementary Figure S2 in Additional file 1. Three embryos, A, B, and C, exhibited normal ploidy. Two reference embryos (D and E) with abnormal chromosomes 13 and 17 were successfully identified. Embryo F with monosomy 6q was also observed. Red and blue dots indicate the copy number of different chromosomes. Each point is at 1 Mb resolution. The green horizontal line indicates an abnormal copy number
