Read the questions and choose from the following, they can be 1 or more:

1. Gap genes
2. Pair-rule genes
3. Segment-polarity genes
4. Hox genes

a) In an embryo from a homozygous Bicoid mutant female, which class(es) of gene expression is (are) abnormal?

b)) If you had a mutation affecting anterior-posterior patterning of the Drosophila embryo in which every other segment of the developing mutant larva was missing, would you consider it a mutation in a gap gene, a pair-rule gene, a segment-polarity gene, or a hox gene?
