Class 10 Biology Chapter 15 Review Exercise

This review exercise is carefully designed to test comprehension and application skills. It includes:

1. Multiple-Choice Questions (MCQs)
   The MCQs focus on important concepts such as:
   • The structure and function of DNA
   • Mendelian inheritance patterns
   • The roles of dominant and recessive alleles
   • Key definitions like genotype, phenotype, and co-dominance
   • The significance of genetic variations in evolution
   Example Questions:
   • What is the term for an organism’s physical traits?
     (a) Genotype (b) Phenotype (c) Karyotype (d) Chromotype
   • Which allele is dominant in pea plants for seed shape?
     (a) Wrinkled (b) Round
2. Short Answer Questions
   These questions require students to explain concepts like:
   • The difference between genotype and phenotype
   • The definition of natural selection
   • Examples of traits in humans (e.g., height, eye color)
     These exercises help reinforce understanding through precise, concise answers.
3. Practice Diagrams
   Students are asked to label diagrams, such as the Watson-Crick model of DNA, encouraging visual learning and memory retention. These illustrations bring theoretical concepts to life and provide a practical angle to genetic learning.
