All of the issues listed - misidentified paternity, conspecific nest parasitism, shared environments, and maternal effects - can contribute to a variation in traits that might be incorrectly attributed to genetic inheritance. Misidentified paternity can make it difficult to determine which traits are actually inherited from a particular parent, while conspecific nest parasitism can lead to the mixing of genetic material between different parents. Shared environments can make it difficult to discern whether a trait is due to genetics or the result of the environment in which an organism is raised, while maternal effects can affect traits independent of the genes a finch inherits from its parents.
