Mendelian Genetics and Heredity explains the fundamental principles governing the inheritance of traits from one generation to the next, based on the experiments of Gregor Mendel. This category focuses on the laws of inheritance, genetic crosses, and inheritance patterns, making it suitable for Class 11–12 students, NEET aspirants, and undergraduate learners.
In this section, you will study:
Mendel’s experiments and contributions to genetics
Laws of inheritance: dominance, segregation, and independent assortment
Monohybrid and dihybrid crosses
Genotype and phenotype ratios
Test cross and back cross
Exceptions to Mendelian inheritance (introductory level)
Application of Mendelian principles in heredity
NCERT-based explanations, diagrams, MCQs, and exam-oriented questions
The content is structured to build strong conceptual foundations, improve cross-based problem solving, and help students perform confidently in school examinations, NEET, and undergraduate assessments.
Develop a clear understanding of Mendelian genetics to master the core principles of heredity and genetic inheritance.
Q. In a test cross, what is the purpose of crossing an individual with a homozygous recessive?
A.
To determine the dominant allele
B.
To identify the genotype of the individual
C.
To produce offspring
D.
To analyze gene expression
Solution
A test cross with a homozygous recessive individual helps determine the genotype of the individual in question.
Correct Answer:
B
— To identify the genotype of the individual
