imprinting

imprinting
n.
1) (in animal behaviour) a rapid and irreversible form of learning that takes place in some animals during the first hours of life. Animals attach themselves in this way to members of their own species, but if they are exposed to creatures of a different species during this short period, they become attached to this species instead.
2) (in genetics) a phenomenon whereby gene expression depends on whether the chromosome is maternal or paternal in origin. For example, both Prader-Willi syndrome and Angelman syndrome are caused by a deletion of the same part of chromosome 15. When the deletion involves the chromosome 15 that came from the father, the child has Prader-Willi syndrome; inheritance of the same deletion from the mother results in Angelman syndrome.
