Yes.

Transgenerational epigenetic inheritance is the transmission of epigenetic markers from one generation to the next i.e., from parent to child, that affect the traits of offspring without altering the primary structure of DNA. In sexually reproducing organisms, much of the epigenetic modification within cells is reset during meiosis through some epigenetic responses that have been shown to be conserved.
Genomic imprinting is a form of epigenetic inheritance whereby the regulation of a gene or chromosomal region is dependent on the sex of the transmitting parent. During gametogenesis, imprinted regions of DNA are differentially marked in accordance with the sex of the parent, resulting in parent-specific expression. This is clearly shown in the given diagram:-
