Anecdotal evidence is described as the evidence that is based entirely upon an individual's personal experiences or observations.
As per the question, a claim based on such evidence is most likely to be <u>biased</u> as anecdotal evidence is based on a limited selection of examples that either support or refute the claim but not supported by any scientific or statistical analysis. Due to this undue bias, <u><em>anecdotal evidence is not considered reliable as it displays the personal opinion, feeling, or experience of an individual</em></u>. Thus, <em>it may be used to negate the general statements but not to support r substantiate a claim or argument</em>.
An organism which has two different alleles of the gene is called heterozygous. Phenotypes (the expressed characteristics) associated with a certain allele can sometimes be dominant or recessive, but often they are neither.
