Why are inheritance patterns more complex than simple patterns Mendel observed?

Mendels studies predicted inheritance in a simple manner by studying traits which were not continuous or polygenic. Hence, the patterns of Mendel's observations were simple.

But there are certain traits which are polygenic that means depending on more than one gene type and there are other traits which are continuous. These kinds of traits have complex inheritance patterns and cannot be predicted through laws of Mendel.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
