A widely accepted hypothesis for the evolution of genomic imprinting is the "parental conflic.

Parents teach offspring critical behaviors that make them more fit for environment. This is taught during the critical period which isa limited time during which imprinting can occur, which is usually at a young age.

Imprinting is important in some aspects of animal behavior, particularly in the development of social bonds and recognition of parental figures. It can play a crucial role in ensuring animals learn necessary behaviors early in life. However, the significance of imprinting can vary depending on the species and its specific behavioral needs.

True. Genomic imprinting involves the selective silencing of specific genes based on their parental origin, while genetic anticipation refers to a phenomenon where a genetic disorder becomes more severe or is detected at an earlier age in successive generations due to an increase in the number of trinucleotide repeats. Both processes involve the inhibition or activation of genes based on specific genetic or parental factors.

No, imprinting is limited to birds and a few other animals. Humans form attachments.
