Forked line method genetics
b) Predict the phenotypic ratios of the offspring using either a punnet square or forked line method. Consider the cross AaBbCC x AABbCc a) How many different gamete genotypes can each organism make? b) Predict the phenotypic ratios of the offspring using either a punnet square or forked line method. Problem 2ACQ: Figure 8.10 In pea plants ...While the forked-line method is a diagrammatic approach to keeping track of probabilities in a cross, the probability method gives the proportions of offspring expected to exhibit each phenotype (or genotype) without the added visual assistance. Both methods make use of the product rule and consider the alleles for each gene separately.
