Rumor has it, Professor Xavier is accepting new recruits.
A breakthrough study has revealed that each one of us receives approximately 60 new mutations in our genome from our parents. Apparently, we’re all mutants.
The report is the first-ever direct measure of new mutations coming from mother and father allowing researchers to answer the question: how many new mutations does a child have and did he get them from mom or dad?
Although much of our variety results from the reshuffling of genes through sexual reproduction, “new mutations” are the ultimate source of new variations. “New mutations” are those that occur in the sperm or egg cells, mutations not seen in our parents.
Finding new mutations though, is extremely challenging given the event’s rarity – only 1 in every 100 million letters of DNA is altered each generation. As such, instead of directly measuring new mutations, previous studies often averaged mutation rates across both sexes or measured them over several generations.
