(a) What is the law of dominance of traits ? Explain with an example. (b) Why are the traits acquired during the life time of an individual not inherited ? Explain.
(a) Law of dominance which is also called Mendel's law of dominance that states that in a heterozygotic cross, one trait will suppress the presence of another trait. Instead of both alleles the dominant allele will be expressed exclusively in the phenotypic ratio.
Example:
where as, T is dominant and t is recessive.
So, the phynotipic ratio is 3:1.
