A BMI of 18.88 would be pretty normal for a 13 year old if not a bit on the lower side already. Usually we consider a BMI between around 18/19 and around 25 to be that of a normal weight person. If it is below theis, we would recommend to eat more, if ti above this we would recommend to eat less. Considering that we're talking about a 13 year old, perhaps it would be better if he/she ate a bit more to supply his body with the necessary nutritional needs.
The type of mutation that will eventually occur is A TO G BASE SUBSTITUTION.
In this type of mutation, what will happen is that, in all the points where adenine base is suppose to be inserted, it is the guanine base that will be inserted there. This is an example of base substitution error in DNA replication.
