In these cases, chimerism may manifest as the presence of two sets of DNA, or organs that do not match the DNA of the rest of the organism. In some cases, hermaphroditic characteristics, in other words, having both male and female sex organs, can be signs of chimerism.
A cognitive bias refers to a systematic pattern of deviation from norm or rationality in judgment, whereby inferences about other people and situations may be drawn in an illogical fashion. Individuals create their own subjective social reality  from their perception of the input.
Since heuristics are mainly used in for reasoning, the types of cognitive biases that heuristics can produce are the biases that reflect the constraints of our reasoning system. Cognitive biases can sometimes be caused by factors other than heuristics; some biases in social cognition, for instance, are the result of the individual trying to feel better about him/herself.
