Give an example of the genotypes of each, for the dragon example. For the genotypes BB, Bb and bb, write the phenotypes that these genotypes would have if the mode of inheritance is simple dominance, if it is incomplete dominance and if it is codominance. If so, describe the relationships. Distinguish between codominance and incomplete dominance in terms of the expression of alleles and the phenotypes from each mode of inheritance. B. Determining Modes of Inheritance Solve the genetics problems that are listed in Appendix G of your Lab Manual.
Answers are in the book.
Geneticists doing applied and basic research need to determine genotypes and modes of inheritance. To determine if the mode of inheritance is simple or incomplete dominance or codominance, you must do a monohybrid cross. Write all of the steps involved in doing a monohybrid cross for the dragon wing color gene, starting with a monohybrid cross of unlike homozygotes and ending with the F2 generation. Assume to start with that the mode of inheritance is simple dominance. Be sure to indicate which individuals are crossed with which, which are parents, and which are offspring.
