Because a mutation that arises is not masked by a normal allele on a homologous
chromosome.
It was important that Neurospora was haploid because it allowed for the study of individual genes. Being haploid means that the organism has only one copy of each gene, making it easier to identify the effects of specific gene mutations on the phenotype. This made it possible for Beadle and Tatum to investigate the relationship between genes and enzymes in their groundbreaking work on the "one gene, one enzyme" hypothesis.
They used Neurospora Crassa (a bread mold). It could grow in a simple medium which helped aid in their research.

There are many different types of molds in existence. These are 5 of the molds commonly found in a house.ASPERGILLUSOver 185 species are appearing in many different colors and are commonly found in American households. It has long flask-shaped spores that can form thick layers or walls of the mold. This creates long chains of mold growth on surfaces.Aspergillus is an allergenic mold, but it is also capable of becoming more toxic depending on the species and the environment affected. It can lead to symptoms like Asthma attacks, lung infections, and respiratory inflammation.ACREMONIUMThis mold typically grows in humidifiers, cooling coils, drain pans and window sealants. It first starts as a small moist mold that turns into a fine powdery substance. Acremonium mold is often pink, grey, orange or white.CHAETOMIUMChaetomium is a mold commonly found in water-damaged homes and buildings. This mold is usually found in a damp or leaking roof, basement or sink and maybe recognizable by its musty odor. This mold causes health effects such as skin and nail infections.AUREOBASIDIUMYou can find this mold growing behind wallpaper or on painted walls or wooden surfaces. Aureobasidium usually develops in pink, brown or black color. As it ages, aureobasidium typically turns a darker brown color. This kind of mold can cause dermatitis or skin rash if directly touched with bare skin.ALTERNARIAThis mold typically grows wherever dampness occurs like showers, bathtubs, and leaking sinks. Alternaria is the most common form of allergenic mold in the world. It’s a velvet-textured mold with dark green or brown hairs. Alternaria is also a common mold species that appear as a result of water damage to a home or building.Hope this helps!

Germline gene therapy involves the modification of germ cells (gametes) that will pass the change on to the next generation. With germ line therapy genes could be corrected in the egg or the sperm that is being used to conceive. The child that results would be spared certain genetic problems that might otherwise have occurred. Because every cell descends from the fertilized egg, every cell in the offspring would possess the transplanted gene. This would be a far more effective way of transferring genes than the ones presently used in somatic cell therapies, where genes into the cells of children or adults usually enter only a small portion of the person's cells and eventually stop functioning.
one gene controls the synthesis of one enzyme

No I doubt whether it is rare, as my school has about 200 copies of The Beadle (we use it for our literature studies). I'm not shure about its availibility though.
Eliezer Wiesel received guidance and mentorship in his studies from Moshe the Beadle, a Jewish mystic and teacher in the town of Sighet where Elie lived. Moshe shared his knowledge and wisdom with Elie, igniting his interest in Jewish mysticism and teachings.
