Plant Breeding and Genetics Multiple Choice Objective Questions (MCQ) and Answers

Plant Breeding and Genetics MCQ or Plant Breeding and Genetics Multiple Choice Questions (बहुविकल्पीय प्रश्न) are Multiple Choice Objective Question asked in different agricultural competition exams.

Apart from an agricultural entrance exam, these questions are also asked in other competition exams too such as exams related with agro-forestry, banking, UPSC etc.

These questions are also included in general knowledge, which also a part of different important exams as a subject.

Importance of The Subject

This is one of the very important subject in B. Sc. Agriculture and M. Sc. Agriculture. In B. Sc. Agriculture, students from the following subjects are eligible after 12th,

1. Students of agriculture.
2. Students of science.
3. Students of mathematics.

Generally, it is easy for the students of science but for the students of agriculture and mathematics most of the topics from this subject are not easy as compared to science-students.

Almost all important entrance exams related with agriculture include topics from plant breeding and genetics in syllabus. Scoring good marks from this subject help in cracking the exam with very good rank. Although, students have to give importance to subjects like agronomy, horticulture, entomology, soil science etc.

Topics of The Posts

1. Fundamentals of Genetics and Plant Breeding.
2. Structure and Function of Cell.
3. Mitosis.
4. Meiosis.
5. Mandellian Genetics.
6. Plant Biotechnology.
7. Tissue Culture.
8. Structure and Functions of Carbohydrates, Proteins, Enzymes, Vitamins.
9. DNA.
10. RNA.
11………..and others.
