Condition Tree of gametes and blastocyst stage embryos. Sperm, GV oocytes, and in vitro-produced blastocysts (In Vitro Blast.) had the highest similarity to each other and grouped together. The second group included SCNT- (NT Blast.), and in vivo-produced blastocysts. Parthenogenetic-produced blastocysts (Parth. Blast.) also clustered with this group. This clustering pattern suggests that the methylation remodeling events of the SCNT-produced blastocysts more accurately mimics the remodeling of the in vivo-produced blastocysts than the remodeling that occurs in the in vitro-produced blastocysts. This condition tree only includes the data where there was at least one difference between the samples, thus the top branch shows a very low correlation. Hypermethylated spots, as compared to the reference, are shown in red and those that are hypomethylated are shown in blue.
