To study the dynamics of 5-methylcytosine and 5-hydroxymethylcytosine in zygotes, the parental origin of the pronuclei needs to be determined. To this end the use of the asymmetric distribution of histone modifications in pronuclei is becoming more popular. Here, we demonstrated that histone 3 lysine 27 di-tri-methylation shows a stable pattern being present in the maternal but not in the paternal pronucleus of bovine zygotes, even in late stages of pronuclear development. In contrast, the pattern of histone 3 lysine 9 tri-methylation is very variable, and therefore cannot be used to reliably determine the parental origin of bovine pronuclei.
