Answer;
-Electron microscopes can not view live cells because the method of preparation is lethal.
Explanation;
-The electron microscope is a type of microscope that uses a beam of electrons to create an image of the specimen. It is capable of much higher magnifications and has a greater resolving power than a light microscope, allowing it to see much smaller objects in finer detail.
-There are many different disadvantages to using a electron microscope for example they are extremely expensive which limits the availability to use them. Furthermore researchers are unable to observe the image in color, as electrons do not possess color, which may not allow the image to be understood easily.
-Additionally the use of the electron microscopes require a large space for example a whole room which may not be feasible.

<h2>Answer is option " 2 & 4"</h2>
Explanation:
- Two types of posterity can be created subsequent to mating: parental and recombinant. Recombinants are created because of the traverse of non-sister chromatids at the hour of gamete arrangement. Here, mating happens between m+g/mg+ female and mg/mg male so the posterity would be separated as follows:
- m+g/mg : Parental
- mg+/mg : Parental
- m+g+/mg : Recombinant
- mg/mg : Recombinant
- m+g+/mg (wild sort) and mg/mg (smaller than usual wings, garnet eyes) are the recombinants thus they were created because of the hybrid occasion.
- Hence,the right answer is option 2 & 4 "wild type and miniature wings,garnet eyes"
If it's letter choice then it would be : all of the above
