Dominance is a genetic relationship between two alleles of the same gene that influences the phenotype of one allele while hiding the function of the other allele. A dominant trait is one that is exhibited in a phenotypic while a recessive trait is one that is suppressed. Co-dominance is the form of dominance caused by the blending of alleles in which the offspring exhibit similar traits to both parents. The codominance pattern of inheritance governs the genes that form the blood types of people. There is one recessive allele (O) and two dominant alleles (A & B). Although the lesson on genetics can be challenging, it will be "a breeze" with the help of our codominance worksheet on blood types. Our Codominance worksheets Blood Types will help you to review your knowledge of blood type inheritance. We have numerous questions to test your understanding of the number of alleles that exist for blood types besides asking you to identify a blood type reflecting codominance. If you are looking for a way to re-teach and provide additional practice when it comes to the codominance blood types, give our codominance worksheet blood types a try. We’re sure that these biology worksheets would be a great reinforcement activity.
