Law of Dominance

The video tutorial explains the concept of inheritance, focusing on dominant and recessive traits, using eye color as an example. It delves into Mendel's experiments with pea plants, illustrating the law of dominance and the 3:1 phenotypic ratio. The tutorial also covers incomplete dominance, using Snapdragon flowers and chicken plumage as examples, highlighting the 1:2:1 phenotypic ratio. Finally, it discusses codominance in human ABO blood groups, explaining how both alleles are expressed equally, resulting in a 1:2:1 ratio.
