6. Which of the following best explains how imprinting influences gene expression and maintains appropriate dosage?

		Imprinted genes are randomly silenced on either the maternal or paternal allele in each cell, leading to monoallelic expression and reduced dosage variability.
		Imprinting involves DNA methylation marks established during gametogenesis that selectively silence one parental allele, ensuring parent- of-origin-specific monoallelic expression.
		Imprinted genes are silenced only if inherited from the mother, preventing maternal overexpression and maintaining balance with paternal alleles.
		Imprinting activates both alleles of growth-promoting genes, ensuring that embryonic tissues have sufficient gene product for rapid growth.
