What Will You Practice in This Principles of Inheritance and Variation Mock Test?

This NEET Biology mock test covers the major NCERT concepts from Principles of Inheritance and Variation.

1. Mendel and His Experiments

Revise Gregor Mendel’s experiments with Pisum sativum and understand the basic principles of Mendelian inheritance.

2. Basic Genetic Terminology

Practice questions on:

• Gene
• Allele
• Dominant trait
• Recessive trait
• Homozygous condition
• Heterozygous condition
• Genotype
• Phenotype

3. Monohybrid Cross

Understand Mendel’s monohybrid cross and the:
