A mutation in the code for a trait may not always change the expression of that trait. What advantage does this provide cells? Ribosomes can produce proteins more quickly.
Cells only need to make a limited number of proteins.
Proteins can switch tasks without a change in the DNA sequence.
Some changes in the DNA sequence will not cause a change in the protein produced.

Some changes in the DNA sequence will not cause a change in the protein produced.

Explanation:

My reasoning is, if the mutation is not expressed then the changes in the DNA sequence will not affect the coding for whatever protein will be produced. The mutation won't affect anything, it is like the mutation is invisible. I hope it helps plus by process of elimination the others would be wrong.

hi~~

i would say that hybridization occurs frequently in nature, because there are many types of hybrids that have occurred naturally, such as the mule (male donkey + female horse)

whats the answer to your question?
