Most genetic diseases are caused by recessive alleles. Why?

Recessive allele is the allele that is not manifested in the individual like the dorminant allele unless the person inherited two copies. In the case of genetic diseases, the individual inherited two recessive alleles that are mutated. The mutation of the two recessive alleles cause genetic diseases. The problems in the recessive alleles cause aberrations in the expression of the genes.

Explanation:

Genetic diseases are inherited disorder which is caused by mutation of genes which caused aberrations in the Gene expression.

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

thats not a question
