Witryna14 maj 2024 · Imprinted genes are genes whose expression is determined by the parent that contributed them. Imprinted genes violate the usual rule of inheritance that both alleles in a heterozygote are equally expressed. Examples of the usual rule: If a child inherits the gene for blood group A from either parent and the gene for group B from … WitrynaFor example, IGF2 which is imprinted in most tissues is expressed from both alleles in the liver and choroid plexus. Similarly, the absence of imprinting in some tissues obviously does not exclude imprinting in other tissues.
