Welcome to Day 9 of our "40 Days 40 Sureshot Topics" series for Class 12 Biology! In this lecture, we explains the concepts that deviate from Mendel’s Laws of Inheritance.
Key Topics Covered:
Incomplete Dominance: Understanding how F1 hybrids show intermediate phenotypes (e.g., Snapdragons / Antirrhinum majus). [01:07]
Co-dominance: How both alleles express themselves equally (e.g., ABO Blood Grouping). [03:15]
Multiple Alleles: When more than two alleles control a single trait. [06:30]
Pleiotropy: A single gene influencing multiple phenotypic traits (e.g., Phenylketonuria). [07:07]
Polygenic Inheritance: Multiple genes controlling a single trait (e.g., Human skin color). [07:23]
This video is essential for students preparing for Class 12 Board Exams and NEET. We break down complex genetic ratios and examples like the cross between red and white snapdragons that results in pink flowers. [01:43]
