The polar lobe produced in 1-cell zygote of the llyanassa snookii is inherited through only one of the two cells in the 2-cell zygote. You want to demonstrate that, as in other snails like llynassa obsoleta, cleavage of zygote generates two daughter cells which are no longer totipotent. Discuss one experiment you could carry out to show such lack of equivalence of two cells in zygote. Clearly describe the expected outcome of your experiment in the answer you provide.
