Key Syllabus Topics and Updates

The NEET Exam syllabus for Principles of Inheritance and Variation remains unchanged, covering Mendelian inheritance, deviations (incomplete dominance, co-dominance, multiple alleles, blood groups, pleiotropy), polygenic inheritance (elementary idea), chromosome theory, chromosomes and genes, sex determination (humans, birds, honey bee), linkage and crossing over, sex-linked inheritance (haemophilia, colour blindness), and disorders (Thalassemia, Down’s, Turner’s, Klinefelter’s syndromes). Our most extensive collection of free chapter-wise NEET mock tests aligns perfectly, sourced from our 25,000+ question bank.

Picture peas revealing dominance, blood groups showing co-dominance, or chromosomes misaligning in Down’s syndrome—our tests simplify these concepts, making Mendel’s ratios or sex determination crystal-clear for NEET’s expectations.

With no syllabus changes, the focus stays sharp—Punnett squares, linkage maps, and disorders like Thalassemia. Our mock tests deliver practice that’s current and precise for Exam, helping you conquer this critical chapter.

How to Score Well in This Chapter

Scoring 20–24 marks is achievable with focused practice, and our most extensive collection of free chapter-wise NEET mock tests is your edge. Start a test—no signup, instant access—and tackle NEET-style MCQs: “What’s the F2 ratio for Mendel’s monohybrid cross?” or “How’s haemophilia inherited?” Solutions are included, accelerating learning. Aim for 1-2 minutes per question—NEET pace—covering co-dominance or Klinefelter’s traits. Diagrams (e.g., Punnett squares, karyotypes) are crucial—our tests train you to sketch dihybrid crosses or label chromosome anomalies accurately.

Link concepts: Mendel’s laws to deviations, linkage to crossing over. Our questions mix basics (e.g., “What’s pleiotropy?”) with application (e.g., “Why’s colour blindness X-linked?”)—hundreds of questions ensure you’re prepped for NEET’s broad scope.

The stable syllabus means you can dive deep—our tests emphasize essentials like multiple alleles or Turner’s syndrome, ensuring your prep is streamlined and effective for those 5–6 questions.

Most Important Topics for NEET

With 5–6 questions, NEET targets these high-yield areas. Our most extensive collection drills them with precision, and here’s a detailed breakdown to make them stick for students:

• Mendelian Inheritance and Deviations: Mendel’s laws (dominance, segregation, independent assortment) predict trait inheritance—monohybrid ratio 3:1, dihybrid 9:3:3:1. NEET asks, “What’s a dihybrid F2 ratio?” (Answer: 9:3:3:1.) Deviations include incomplete dominance (e.g., snapdragon’s pink flowers, 1:2:1), co-dominance (e.g., AB blood group, both traits expressed), multiple alleles (e.g., ABO blood groups, I^A, I^B, i), and pleiotropy (e.g., sickle-cell anemia affects multiple traits). Expect “What’s co-dominance’s result?” (Answer: both alleles expressed.) Our tests cover MCQs like “Calculate monohybrid ratio” with Punnett squares and questions like “Match blood group to genotype” (AB: I^A I^B), ensuring you master Mendel and deviations.
• Chromosome Theory and Sex Determination: Chromosomes carry genes—Sutton-Boveri’s theory links meiosis to inheritance. NEET tests “What’s chromosome theory’s basis?” (Answer: genes on chromosomes.) Sex determination varies: humans (XX/XY, females homogametic), birds (ZW/ZZ, males homogametic), honey bees (haplo-diploid, males from unfertilized eggs). Expect “What’s honey bee male’s origin?” (Answer: haploid egg.) Our tests drill questions like “Identify human karyotype” (46, XX) with visuals—e.g., “Label XY chromosomes”—covering mechanisms across species.
• Linkage, Crossing Over, and Sex-Linked Inheritance: Linkage keeps genes on the same chromosome inherited together; crossing over shuffles them, forming recombinants—NEET asks, “What’s crossing over’s outcome?” (Answer: new gene combos.) Sex-linked traits (X-linked) like haemophilia (recessive, X^h) and colour blindness (X^c) affect males more. Expect “Who’s haemophilia’s carrier?” (Answer: XX^h female.) Our tests include questions like “Map linkage distance” with diagrams and MCQs like “Trace colour blindness pedigree,” ensuring you grasp recombination and X-linked patterns.
• Mendelian and Chromosomal Disorders: Mendelian disorders like Thalassemia (autosomal recessive, hemoglobin defect) contrast chromosomal disorders—Down’s syndrome (trisomy 21, 47 chromosomes), Turner’s (XO, 45 chromosomes, female sterility), Klinefelter’s (XXY, 47 chromosomes, male infertility). NEET tests “What’s Down’s cause?” (Answer: extra chromosome 21.) Expect “What’s Turner’s karyotype?” (Answer: 45, XO.) Our tests cover MCQs like “Match disorder to trait” (Thalassemia: anemia) with karyotype visuals—e.g., “Label trisomy 21”—ensuring you nail genetic defects.
• Polygenic Inheritance (Elementary Idea): Traits like height or skin color result from multiple genes—unlike Mendel’s single-gene traits. NEET asks, “What’s polygenic inheritance’s trait?” (Answer: continuous variation.) Our tests include questions like “Identify polygenic example” (Answer: height) with graphs showing bell-curves, keeping prep simple yet aligned with NEET’s basic focus.

This section’s depth—covering Mendel to disorders—pairs with our tests’ visuals (e.g., “Sketch Punnett square”) and questions (e.g., “What’s Klinefelter’s trait?”), ensuring you ace NEET’s 20–24 marks with ease.

Common Mistakes to Avoid

Don’t lose those 20–24 marks—our mock tests fix these pitfalls:

• Ratio Errors: Monohybrid (3:1) vs. incomplete dominance (1:2:1)? Our questions clarify—e.g., “Pink flowers are 1:2:1.”
• Inheritance Mix-Ups: Co-dominance (both traits) vs. multiple alleles (blood groups)? Our MCQs drill—e.g., “AB blood shows co-dominance.”
• Sex-Linked Confusion: Haemophilia (X-linked) vs. Thalassemia (autosomal)? Our tests repeat—e.g., “Haemophilia skips females.”
• Disorder Blunders: Down’s (trisomy) vs. Turner’s (XO)? Our questions hit—e.g., “Klinefelter’s is XXY.”

Hundreds of questions erase errors, with solutions explaining why, say, crossing over creates recombinants, keeping prep aligned with the syllabus.

Quick Tips to Ace This Chapter

Crush Inheritance with these—our mock tests lock them in:

• Ratio Note: “3:1, 1:2:1, 9:3:3:1”—monohybrid, incomplete, dihybrid. Test with our MCQs.

• Disorder Flash: “T-D-T-K”—Thalassemia (autosomal), Down’s, Turner’s, Klinefelter’s (chromosomal). Our questions hit—e.g., “XO is Turner’s.”
