Questiоn 36 -39 аre bаsed оn the fоllowing scenаrio: A geneticist is investigating the inheritance of flower color in a population of plants. According to Mendelian genetics, the expected phenotypic ratio for a dihybrid cross is 9:3:3:1 (9 individuals with AA, 3 with Aa, 3 with aA, and 1 with aa). After conducting a dihybrid cross, the geneticist observed the following results: Phenotype AA: 210 individuals Phenotype Aa: 70 individuals Phenotype aA: 80 individuals Phenotype aa: 40 individuals
