Will the number of mutations for the entire genome always be the same? Why, or why not?
No, the number of mutations will not be same for the entire zenome. There will be huge number of mutations in which some are harmful and some are useful. each individual mutation is rare when it first occurs, often there is one copy of it in the gene pool of an entire species. the hamrful mutations get eliminated before their carriers are even born, and useful mutations will enter population as alternative versions of genes. most of the new mutations are lost because they are rare. very small effects on survival and reproduction may effect the long term rates at which different mutations accumulate in particular genes and particular sites within genes.
