The 'Evolutionary Developmental Biology' section describes a fly mutation resulting in legs emerging from its head. What type of gene is specifically mentioned as being mutated to cause this effect?

  • A: A homeotic gene.
  • B: The *bicoid* gene.
  • C: A gene controlling dorsal-ventral axis formation.
  • D: A gene responsible for maternal mRNA degradation.

Explanation

The 'Evolutionary Developmental Biology' section explicitly states that the 'fly with legs emerging from its head in Figure 18.20 is the result of a single mutation in one gene, a homeotic gene.'
