Quizplus · Accepted Answer

The experiments shown are testing the hypothesis that cytoplasmic factors necessary for normal development are segregated in the zygote. Experiment 1 had unequal distribution of cytoplasmic factors which resulted in one normal embryo and one clump of undifferentiated cells. Experiment 2 had complete segregation of cytoplasmic factors which resulted in two clumps of undifferentiated cells. Therefore, the correct answer is B.
