ARS Examination and NET Examination will be held separately once and twice a year respectively.

International Journal of Plant Breeding and Genetics publishes original research covering all areas of theoretical and applied plant breeding and genetics.

Some content from the given attachment is given here:

Unit 1: General Genetics and Plant Breeding
Mendelian inheritance. Cell structure and division, Linkage, its detection and estimation. Epistasis. Gene concept, allelism and fine structure of gene. Extra chromosomal inheritance.

The Civil Services Examination is a nationwide competitive examination in India conducted by the Union Public Service Commission for recruitment to various Civil Services of the Government of India, including the Indian Administrative Service, Indian Foreign Service, and Indian Police Service.

Plant Breeding & Genetics topics are covered in UPSC Prelim. & Main Examination of Agriculture.

Below I am providing you the UPSC Question Papers of Prelim. & Main Examination Of Agriculture:
