imprinting

*Somatic cells of both males and females normally contain both the maternally and paternally imprinted chromosomes.

**In gametes the imprint of the genes contributed by the opposite-sex parent at the time of conception is converted to the imprint of the sex of the offspring; i.e., in a male offspring the maternal imprint is converted to a male imprint in all sperm and in a female offspring the paternal imprint is converted to a female imprint in all eggs. This conversion process is controlled by the imprinting center, located within the imprinted region itself.
