1.	Explain the statement.Law of dominance is not universally applicable.
Answer» Law of dominance is not universally applicable. In a cross between two organisms pure for any pair (or pairs) of contrasting characters, the character that appears in F₁ generation is called dominant and the one which is suppressed is called recessive. In many cases, the dominance is not complete or absent. Phenomenon of dominance is significant as the harmful recessive traits are masked, i.e. not expressed in the presence of its normal dominant allele. e.g. In humans a form of idiocy, diabetes and haemophilia are recessive characters. Thus, law of dominance is significant and true, but it is not universally applicable.
