Given: bicoid genes are maternal genes; kruppel genes are gapgenes, even-skipped genes are pair rule genes, gooseberry genes aregooseberry. Predict the effect of scenarios below on expressionlevels of each of these gene classes in the embryo described (willexpression increase, decrease, or be unaffected?) and explain thereason for your prediction.
a. a fly embryo has a mutation that blocks expression of thekruppel gene
b. a fly embryo has a mutation that blocks expression of the bicoidgene.
c. a fly embryo has a mutation that increases expression of theeven skipped gene.
