1.1 Compare the expression pattern of Lfng in one period of somitogenesis between the WT and DI13Pu mutants (panels a-f), where is the gene expressed and what is different? (3 points) 1.2 In panels g and h, the embryo was bisected and one side fixed right away and the other incubated for ½ of a single somitogenesis cycle. Compare the change in Lfng expression in the two genotypes at time 0 and time +45. What can we conclude from this experiment? (2 points)
