The video tutorial by Mr. Vev covers complex patterns of inheritance, including incomplete dominance, co-dominance, multiple alleles, and polygenic traits. Incomplete dominance is illustrated with beta fish, where heterozygous individuals show a mix of traits. Co-dominance is explained using corn color, where both alleles are expressed simultaneously. Multiple alleles are discussed with examples like bunny coat color and human blood types. Finally, polygenic traits such as eye color and skin color are explored, highlighting the influence of multiple genes.
