There are cases,particularly in fruit flies,in which a perfectly normal body part grows in an area where it should not grow.Extra pairs of wings and legs growing in the antennae location are some examples.Select the statement that best describes this phenomenon.
A)These mutations occur as a result of specialized development called determination in which the gene determining a specific factor will become totipotent.
B)These mutations occur as a result of differentiation of these tissues at the incorrect time during development,which causes a mix-up in signals and protein production in those tissues.
C)These mutations occur as a result of homeotic gene mutations.
D)These mutations occur as a result of gap gene mutations.

Question

This phenomenon is known as homeotic transformation or homeosis, which occurs due to mutations in homeotic genes. Homeotic genes are responsible for controlling the identity of body segments during embryonic development. Mutations in these genes can cause the development of a body part in the wrong location, leading to the growth of extra pairs of wings or legs in fruit flies.
