6. Blood type is a phenotype caused by sugars attached to lipids on the \( \triangle \) ABO Bood Grow Troe-1 Antions surface of red blood cells. Humans have three ABO blood type alleles \( \mathrm{A} \) and \( \mathrm{B} \) are codominant, and \( \mathrm{O} \) is recessive. Use Punnet squares to show all the possible crosses and the phenotypes that could result from a mating between an individual with blood type \( \mathrm{A} \) and one with blood type \( \mathrm{B} \) ? Draw a diagram to show all possible combinations of \( \mathrm{A}, \mathrm{B} \), and \( \mathrm{O} \) alleles. Label each genotype with its phenotype and determine the phenotypic ratios (assuming that \( \mathrm{A}, \mathrm{B} \) and \( \mathrm{O} \) all have the same frequency).
