In homeotic mutants: Group of answer choices one body structure is missing. one body structure has been changed into another. one body structure has been duplicated. one body structure has significantly increased in size. the organism is infertile.
In homeotic mutants, one body structure has been changed into another
Homeotic genes provide identity of organ and they become permanently switch off after completion of their work
In Drosophila, these genes are tightly regulated by the activity of polycomb genes and is present in two patches, one path constitute antennapedia complex whereas another patch constitute bithorax complex
Antennapedia complex expresses in the second thorax segment and is responsible for the formation of legs
Besides formation of thorax legs it also expresses in the area of head
A mutation in antennapedia lead to the formation of legs on the place of antenna
