"Dots" (if referring to "Drosophila," commonly known as fruit flies) are considered ideal for studying Mendelian genetics primarily because they follow Mendelian rules perfectly. They have a relatively simple genetic structure, a short generation time, and produce a large number of offspring, which makes it easier to observe the inheritance patterns of specific traits. This allows researchers to effectively study genetic concepts such as dominance, recessiveness, and segregation of traits. Thus, the correct option in this context would be:
They follow Mendelian rules perfectly.
