NEET 2016 Biology Evolution Questions

Use this page to connect the official 2016 paper with current Biology practice. NeetVellum does not claim a chapter appeared in that paper until the official question and final key have been mapped.

Original practice preview

These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.

Example 1 · difficulty 1/5

In his 1953 spark-discharge experiment simulating conditions on primitive Earth, Stanley Miller passed electric discharge through a sealed gaseous mixture held at about 800°C. Which combination of gases did he use?

A. Methane, ammonia, hydrogen and water vapour
B. Carbon dioxide, nitrogen, oxygen and water vapour
C. Methane, oxygen, hydrogen sulphide and water vapour
D. Ammonia, nitrogen, carbon dioxide and ozone

Example 2 · difficulty 2/5

In a large randomly mating population at Hardy–Weinberg equilibrium, 16% of individuals express a recessive trait. The expected frequency of heterozygous carriers in this population is:

A. 0.16
B. 0.48
C. 0.36
D. 0.24

Example 3 · difficulty 3/5

In human populations, newborns with birth weights much lower or much higher than the average show increased infant mortality, while babies near the mean survive best. Over generations this keeps the mean birth weight unchanged. This pattern of selection is called:

A. Stabilising selection
B. Directional selection
C. Disruptive selection
D. Genetic drift

Frequently asked questions

Are these official NEET 2016 Biology Evolution PYQs?

No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.

How should I use the NEET 2016 paper?

Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
