LAW OF DOMINANCE

Asked by  | 7th Sep, 2008, 08:13: PM

Expert Answer:

It is one of the laws governing the inheritance of characters. In a cross between 2 organisms pure for any pair of contrasting characters, the character which appears first in the hybrid of F1 generation is called dominant and the one which is suppressed is called recessive.

For eg. - In the crossing of pure tall variety of pea plant with pure dwarf, only tall character appeared in F1c generation, hence tallness is dominant over dwarfness.
