Explanation:

Proportional representation seeks to create a representative body that reflects the overall distribution of public support for each party. Constitution has adopted the system of proportional representation in the case of Rajya Sabha.

In proportional representation, elections are held in  a manner that ensures that number of seats won by a party or group of candidates is proportionate  to the number o0f votes received. This ensures a wider representation of diverse opinions in an elected assembly reflecting a true democracy. The proportional representation system rarely results in one party holding an absolute majority. It requires political parties to compromise and build consensus. Whereas, the el;ection of a candidate on the basis of majority of votes he would get is a feature of territorial representation system.
