Overview
Genomic imprinting is a fascinating aspect of genetics that highlights how the origin of a gene can influence its expression. Unlike typical inheritance, where both alleles contribute equally, imprinting results in the silencing of one allele based on whether it is inherited from the mother or fathe...
Key Terms
Example: In genomic imprinting, the gene from the mother may be silenced while the father's gene is active.
Example: Epigenetic modifications can affect how genes are turned on or off.
Example: In genomic imprinting, DNA methylation can silence one allele of a gene.
Example: An individual may inherit one allele for blue eyes from one parent and one for brown eyes from the other.
Example: Individuals with Prader-Willi syndrome may experience obesity and developmental delays.
Example: Angelman syndrome is characterized by severe developmental delays and speech impairments.
