Explain how the different forms of the gene produce different colours of coat.

Skin colour is a good example of polygenic (multiple genes) inheritances. Skin colour is determined by the amount of the dark colour pigment melanin in the skin. This trait is determined by at least three genes. The genes that determine skin colour have two alleles each and are found on different chromosomes.

The gene has 6 colours of coat.

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
