Codominance and Incomplete Dominance: Non-Mendelian Genetics

Some traits don't follow the rules of Mendelian Genetics! This tutorial explains the concepts of co-dominance and incomplete dominance; two common exceptions to traditional genetics. Organisms that inherit traits via complete dominance will show the dominant trait in their phenotype. In this case, it would be a blue phenotype. Only one allele is dominant. Organisms that inherit traits via co-dominance will display BOTH phenotypes; in this case yellow and blue polka dots. BOTH alleles are dominant. A real life example is cow coat color. A red cow crossed with a white cow will produce a calf that has red and white patches on its coat, a pattern called "roan". Organisms that inherit traits via incomplete dominance will display a BLEND of phenotypes. In this case, the offspring would be green, a combination of blue and yellow. Neither allele is completely dominant. Real life examples include snapdragon flowers; a red flower crossed with a white flower will produce a pink flower. 00:00-00:21 Introduction 00:22-00:45 Punnet Squares Complete Dominance 00:45-00:56 Non Mendelian Genetics 00:56-1:41 Types of Dominance: Homozygous Dominant 1:41-1:51 Types of Dominance: Homozygous Dominant 1:51-2:38 Types of Dominance: Heterozygous 2:38-3:02 Codominance: Roan Cows & Blood Type 3:02-3:20 Incomplete Dominance: Flower Petals & Hair Texture 3:20-4:09 Definitions of Complete, Codominance and Incomplete Dominance Avoid plagiarism!
