NCERT Class 10 Science Chapter 8 Heredity Test Mock Test
This free online test covers Chapter 8, Heredity, from the NCERT Class 10 Science textbook. The 25 questions are written directly from the chapter — definitions, processes, worked examples and the points the book italicises — so a score here tells you how much of the chapter actually stuck, not how well you guess. Each answer carries an explanation that says why the right option is right and why the other three fail, which is where most of the learning happens. Attempt it after your first read of the chapter, then again before the exam. There is no negative marking, and you can review the full solution the moment you submit.

Sample Questions
Q1.The chapter contrasts a field of sugarcane with a population of human beings in order to make the point that:
- ASexually reproducing organisms show far more distinct variation between individuals than asexually reproducing ones
- BPlants cannot inherit traits from a previous generation, while animals can
- CAsexually reproducing organisms show far more distinct variation between individuals
- DVariation is produced only during sexual reproduction and never during asexual reproduction
Q2.If one bacterium divides and the two resulting bacteria divide again, the four individuals produced would be:
- ACompletely identical, since asexual reproduction copies DNA perfectly
- BHalf of them like the parent and half of them entirely different
- CExtremely varied, since each division doubles the number of differences
- DVery similar, with only minor differences generated by small inaccuracies in DNA copying
Q3.Inheritance from the previous generation provides the next generation with:
- ABoth a common basic body design and subtle changes in it
- BOnly newly created differences, with no shared body design
- CA body design chosen by the environment rather than by the parents
- DA common basic body design with no changes at all
