Principles of Inheritance Part 2 | Test Cross, Dominance Types, Multiple Alleles & Pleiotropy | NEET

Описание: Welcome to Principles of Inheritance & Variation – Part 2 (Deep Dive Series) for NEET Biology!

In this session, we explore some of the MOST important genetics concepts for NEET, including Test Cross, Dominance Types, Multiple Allelism, and Pleiotropy, explained using NCERT logic and clear examples.

This is a must-watch for NEET 2025/2026 aspirants aiming for perfection in Genetics.

🧬 What’s Covered in Part 2:
🔹 Test Cross

• Purpose of a test cross
• Homozygous recessive logic
• How to detect genotype
• Applications in NEET
• Punnett square clarity

🔹 Complete Dominance

• Classic Mendelian dominance
• TT × tt example
• Phenotype vs genotype relationship
• 3:1 and 1:2:1 logic

🔹 Incomplete Dominance

• Blending effect

🔹 Multiple Allelism

• Three or more alleles of a gene
• ABO blood group as NCERT example
• IA, IB codominance
• Universal donor & recipient logic
• High-yield MCQ traps

🔹 Pleiotropy

• One gene → multiple effects
• Examples from NCERT
• How pleiotropy differs from epistasis
• Why NEET loves this topic
