Describe the differences and similarities in the gene families used by plants and animals to establish the body axis and to regulate gene expression of these gene sets.
Drag the appropriate traits to their respective bins.
Three respective bins: 1. Specific for plants. 2. Specific for animals 3. Common for plants and animals
Traits are following:
MADS-box proteins
Three classes of homeotic genes (A, B, and C)
Homeodomain-containing proteins
Using regulatory genes encoding transcription factors
Formation of organs is determined by regulatory genes expressed in overlapping domains
Mutations causing organ formation in wrong place
Gap and Pair-Rule genes
Regulation of homeotic genes by chromatin structure

2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...
