The Drosophila homeotic mutation spineless aristapedia (ssᵃ) results in the formation of a miniature tarsal structure (normally part of the leg) on the end of the antenna. What insight is provided by (ssᵃ) concerning the role of genes during determination?

Everyone. Let's take a look at this question together. What is the normal structure on which the miniature tar cell structure is formed due to the S S A mutation? So this miniature tar cell structure, we know tar cell means that it is normally found on the legs of insects. But when we have this S S A mutation, which the S S A mutation is the spineless a recipe. A mutation. It is a home idiotic mutation which causes the formation of the miniature parcel structure to form on the and of the antenna of the insect instead of being formed on the legs due to that mutation. So answer choice C is the correct answer because we know that the tar cell structure is normally found on the legs of the insects and are used for walking and gripping surfaces. But in the case of this S a mutation or the spineless Arisa PD A mutation, it results in the formation of that miniature tar cell structure on the end of the antenna of the insect. So answer choice C is the correct answer. I hope you found this video to be helpful. Thank you and goodbye.
