Fathers Pass On Four Times As Many New Genetic Mutations As Mothers, Says Study (theguardian.com)

An anonymous reader quotes a report from The Guardian: Children inherit four times as many new mutations from their fathers than their mothers, according to research that suggests faults in the men's DNA are a driver for rare childhood diseases. Researchers studied 14,000 Icelanders and found that men passed on one new mutation for every eight months of age, compared with women who passed on a new mutation for every three years of age. The figures mean that a child born to 30-year-old parents would, on average, inherit 11 new mutations from the mother, but 45 from the father. Kari Stefansson, a researcher at the Icelandic genetics company, deCODE, which led the study, said that while new mutations led to variation in the human genome, which is necessary for evolution to happen, "they are also believed to be responsible for the majority of cases of rare diseases in childhood." In the study published in Nature, the researchers analyzed the DNA of 1,500 Icelanders and their parents and, for 225 people, at least one of their children. They found that new mutations from mothers increased by 0.37 per year of age, a quarter of the rate found in men. While the vast majority of new mutations are thought to be harmless, occasionally they can disrupt the workings of genes that are important for good health.

I guess this means it's the man's fault

All cis-privileged men are evil and always to blame

No. Not true. This story is lies. Fake news. Everybody knows that men and women are exactly the same at everything. Claiming otherwise is sexist and misogynist and racist and fascist and placist and bassist. You are Nazis and monsters and white supremacists. Retract this article immediately or we're going after your sponsors. Die in hell.

Ideally, each rescue boat should have a ratio of ten women for each man.

It is, you know, a sacrifice required for the future of the human race. I hasten to add that since each man will be required to do prodigious...service along these lines, the women will have to be selected for their sexual characteristics which will have to be of a highly stimulating nature.

female gametes are 100% present at birth

That's recently been found to be untrue.

Not quite. It depends greatly upon the health of the female in the years just prior to puberty. A more concise explanation of ovogenesisis here. This is indeed news for most nerds of the computer kind but then again we do understand the concept of having soldered in ram that cannot be increased. With male nerds the problem lies in the waste of excess male gametes while thinking about the physical aspects of a females reproductive organs. Thus reducing the quantity of male gametes available when the occasion actually occurs. So we do not reproduce as frequently as males who do the real thing, a situation which in theory could reduce the population of nerds in the long run.

So the Catholics had it right all along? Every sperm is sacred? Wasting it won't so much make you blind as make you wish you were so you don't have to look at your mutated kids?
