JAC Class 12 Biology Question Paper 2016 with Solution

About this paper

This is the Jharkhand Academic Council (JAC) Class 12 Biology paper from the 2016 board examination, with answers given under each question. It has a Botany section and a Zoology section, each with ten multiple-choice questions (Group A), three very short answer questions (Group B), three short answer questions (Group C) and two long answer questions (Group D) that each offer an 'Or' alternative. Match-the-columns items appear in both sections, and the Zoology part asks students to label a diagram of a human sperm. Long answers cover sex-linked inheritance in Drosophila, DNA structure, Mendel's laws, the role of FSH and LH in gamete formation and the pond ecosystem. Marks and time are not printed.
