The regulative ability of the
limb bud has recently been highlighted by a remarkable experiment of nature. In
numerous ponds in the United States, multilegged frogs and salamanders have
been found. The presence of these extra appendages has been linked to the
infestation of the larval abdomen by parasitic trematode worms. The eggs of
these worms apparently split the developing tadpole limb buds in several
places, and the limb bud fragments develop as multiple limbs. This shows:
A. The
limb field represents a harmonious equipotent system.
B. The
limb field do not represents harmonious equipotential system because different
types of genes express during proximal to distal growth.
C. The
limb field represents coupled system wherein one gene maintain the expression
of other genes.
D. The
limb field represents a harmonious equipotent system because only Hox genes
expresses all along the limb axis.
E. The
limb field represents cells of the limb region can be instructed to form any
part of the limb.
Which of the following statements are correct?
