Mutations in genes of the _______ gene class often result in the omission of several contiguous larval segments in flies.
A) maternal effect
B) gap
C) pair rule
D) segment polarity
E) Hox

Question

Quizplus · Accepted Answer

Mutations in gap genes can result in the omission of several contiguous larval segments in flies. Gap genes establish several broad areas along the anterior-posterior axis of the developing embryo, and mutations in them lead to the loss of a continuous segment region. Mutations in maternal effect, pair rule, segment polarity, or Hox genes can have different effects on fly development.
