Since mice embryos with loss- of- function Hox mutations result in homeotic alterations, then introduction of such a mutation might cause ___________.
A) pointed rather than rounded ears
B) behavioral alterations causing limb shaking
C) a change in fur coloration along the dorsal midline
D) paralysis of hindlimbs but not forelimbs
E) ribs on normally rib- less vertebrae

Question

Quizplus · Accepted Answer

Hox genes are crucial for determining the body plan and the identity of body parts during embryonic development. Loss-of-function mutations in these genes can lead to homeotic transformations, where one body part is transformed into another. For example, causing ribs to grow on normally rib-less vertebrae is a classic example of a homeotic transformation, which is directly related to the role of Hox genes in specifying the identity of different segments of the body.
