This video tutorial introduces non-Mendelian genetics, focusing on incomplete dominance, codominance, and blood typing. Incomplete dominance is explained as a genetic scenario where alleles blend to create a mixture, exemplified by flower color mixing. Codominance is described as both alleles being expressed simultaneously, illustrated with cow color patterns. The video also covers blood typing, detailing the genetic basis of blood types and how they demonstrate codominance. The tutorial includes example problems to reinforce understanding of these genetic concepts.
