Question

Would a gene with most mutaions on the 3rd codon, most mutations on the 1st and 2nd codon, no mutation, or equal amounts of mutations on all three codons undergo diversefying election? Why? Explain your reasoning why the answer is correct and why the others are not.

Answer 1

Unless the mutations in the gene can cause a benefit in the function of that gene it will not be a diversifing election.If there is no mutation the gene will function in its native form.But if a mutation has occured and if that mutation can cause no function of the gene then that is not elected no matter it happens in which codon.So we cannot say if that mutation is elected based on which codon it is happening.We can only say that if that gene can produce its protein like it was producing or may be it can produce more ,thus increasing its survival ability.
