Spontaneous mutations

[deffchonka]

The most part of spontaneous mutations don't occur in the phenotype because they (are):

- harmful,

- healthy,

- dominant,

- recessive,

- neutral,

- occur in the noncoding DNA,

- include packing processes only.

 

Neutral: the most part of mutations is neutral.

Recessive: if they don't occur they are recessed.

 

Am I wrong?

The last one "include packing processes only" - I'm not sure.

I'll be grateful for any assistance.

Well, the language here is important. Does the question ask what most types of mutations are (i.e. in terms of frequency?). Now, based on that, what does a dominant or recessive mutation look like and how would that affect their frequency? Are they common?

 

Another important bit is which organism you are talking about. I assume humans? How many genes do humans have, what is the average size of the genes and how large is the entire genome. Can you deduce what type of mutation would be most common?
