MHT CET PYQs for Principles of Inheritance and Variation with Solutions: Practice MHT CET Previous Year Questions

Inheritance and Variation is a Class 12 chapter in the Biology section of the MHT CET for candidates who are preparing for the PCB (Physics, Chemistry, and Biology).

The key topics covered in Inheritance and Variation PYQs are:

Mendelian laws, monohybrid and dihybrid crosses
Sex-linked inheritance and haemophilia
Chromosomal disorders and non-disjunction
Blood groups and Rh incompatibility
Linkage and crossing over

Practising Inheritance and Variation MHT CET PYQ helps candidates to understand question pattern, improve calculation speed, and identify concepts which were asked in previous exams.

Based on the MHT CET Biology papers in the PDF, Inheritance and Variation recorded 25 questions, and 14 of them came in the 2025 papers. Each Biology question carries 1 mark.

Question Style in MHT CET Inheritance and Variation PYQs

Every question in this PDF is a single-correct MCQ. Some ask for a probability or a ratio, and the rest are theory questions or statement based questions.

Question Style	What it Tests
Crosses and ratios	The number of heterozygous offspring when two heterozygous plants are crossed, and what a given ratio in a dihybrid cross denotes
Sex-linked inheritance	The probability of a colour blind son when a colour blind male marries a normal visioned female
Chromosomal disorders	The syndrome caused by non-disjunction of the X chromosome during the formation of the ovum
Blood groups and population genetics	What happens when Rh antigens are introduced for a second time, the percentage of homozygous recessive and heterozygous organisms for a given allele frequency, and a table of ABO blood groups
Test cross and linkage	What a test cross is used to confirm, and the percentage of parental type offspring in a Drosophila cross

How to Use the Inheritance and Variation PYQ PDF for MHT CET

Start with the 2025 papers first, because they hold 14 of the 25 questions.
Practise the Punnett square for monohybrid and dihybrid crosses until the ratios 3:1 and 9:3:3:1 are automatic.
Learn the Hardy-Weinberg equation p² + 2pq + q² = 1 for the questions on allele frequency.
Solve year-wise PYQs by timing yourself, as time management is crucial.
Re-attempt only the questions you got wrong, and note the term or fact you missed.
