这样产生的胎儿要么主要是父方的基因表达，要么主要是母方的基因表达。

The resulting fetuses consisted of either mostly paternally or mostly maternally expressed genes.

父性表达基因3）是一个印迹基因，只有来源于父方的等位基因才表达。

Part I Expression of PEGS in GliomasPEG3 (Paternally Expressed Gene 5) is an imprinted gene of which only the paternal allele is expressed.
