Beyond Mendelian Genetics Complex Patterns of Inheritance

The video revisits Mendelian genetics, exploring genotypes, phenotypes, and the limitations of dominant and recessive allele models. It covers incomplete dominance, co-dominance, and multiple alleles, using examples like snapdragons and human blood types. The video delves into pleiotropy, epistasis, and polygenic inheritance, highlighting complex genetic interactions. It concludes with the influence of environmental factors on phenotypes, broadening the understanding of inheritance beyond Mendel's initial findings.
