Detailed explanation-1: -In it, he showed that young ducks and geese could be “imprinted” on virtually anything-from people to colored balls-during their first days of life. Such “programming” probably evolved to help young birds recognize and stick close to their parents for safety.

Detailed explanation-2: -Birds do not automatically know what they are when they hatch – they visually imprint on their parents during a critical period of development. After imprinting, they will identify with that species for life. Imprinting for wild birds is crucial to their immediate and long-term survival.

Detailed explanation-3: -These include Prader-Willi and Angelman syndromes (the first examples of genomic imprinting in humans), Silver-Russell syndrome, Beckwith-Weidemann syndrome, Albright hereditary osteodystrophy and uniparental disomy 14 [1, 2].

Detailed explanation-4: -Imprinting and subsequent latchment is a primary stage of emotional and neurobehavioural development in which the infant recognises its mother through oral tactile memory for continuing evolutionary survival.
