why dont genes causing autism and StPD disappear if their hosts dont reproduce?
>>10463270Your image is an incorrect version of this one.
>>10463270Genes barely matter.
>>10463270Evolution and race don't exist. What a surprise
autism is increasing because people have babies at a later date, since female loses reproductive ability of eggs. isn't this widely known? unnecessary bait thread
>>10463289Wrong. The woman's age has no affect on the development of autism.Only nondisjunction increases which result in chromosomal disorders. Autists don't have chromosomal disorders
>>10463307as parents get older there is an increase in mutation rate, increasing chance something fucks up in chromosomesit is either male or female, I forgot the exact process in which mutation occurs, but what I do know is that the rate of which people get autism increases as rate of parental age increasesso if you want to fuck and raise kids stop fucking waiting so long
>>10463277protip:half your age plus seven rule>>10463283stfu fucking faggot>>10463289autism =/= down's syndrome
>>10463322you imply autism isn't a poorly understood concept that isn't used interchangeably for lots of things and isn't used as an umbrella term for lots of issues correlated to autism, so I tend to not get hooked on terminology
>>10463319It's male parents not female parents that are responsible for their kids autism
>>10463379IIRC autism risk correlates with older fathers and not older mothers, so if you're not actually a chad and have your kids in your 20's, all your tryharding to settle down in your 30's will punish you with autistic kids.But I might be thinking of schizophrenia.
>>10463359which in male parents? it's a fairly poorly understood concept. all I know is that as parents get older there is increase in lots of problems since higher chance of mutationsits a big society problem because kids waste their youth in higher education and only get a chance to fuck once they hit their late 20's-sometime in 30's
>>10463270Recessive autistic genes in people who dont have the mental disorder active.
>>10463388Female eggs have already been differentiated so mutations don't occur there.Males constantly produce sperm cells so the mutations are there in the germline.>>10463379Medical genetics classes at university
>>10463394>medical geneticsis that the entry level mendelian shit or later stuff like molecular genetics
What the fuck is this graph? Can someone give me the methodology of construction?
>>10463410I don't know. I'm not American.
>>10463359wikipedia says that age of both parents play part
>>10463270 roasties reproducing post 30
>>10463322>protip:>half your age plus seven rulecringe
>>10463487Weird. My professor didn't say that.
>>10463630s/he probably forgotnobody is perfect
>>10463639Explain how the age related mutations could take place in females
>>10463642eggs accumulate mutations like any cell, anon.
>>10463728But they don't divide from the moment girls are born.
>>10463742You cannot accumulate mutations unless you are replicating DNA for division
>>10463747what kind of school did you go to?
>>10463270Because we do reproduce, you ignorant imbecile. Also, to all of you imbecilic fucks arguing about causality, studies show that there is a greater hereditary component than anything else, certainly with high-functioning autism and Asperger's syndrome as traits run in families, even in those without enough traits to be considered high enough for a diagnosis on the autistic spectrum.
>>10463779im stpd and i dont reproduce
>>10463797why do you think we haven't sequenced dinosaur DNA yet?
>>10463861I'm AS and do.
>>10463270Because psychology is a meme that only barely describes personality traits. Due to the recent diagnosis boom, more than 50% of individuals are classified as "mentally ill," which has only inflated this number over time due to the normalization of abnormality.Previously much of this behaviour would be minimized by ostracism and peer pressure, but as humanity have become more connected, we have introduced various safe spaces which either tolerate or encourage such behaviour TL;DR: Not science or math
>>10463951Idk ostracism and isolation tend to be worse for mental health, don't they?Not that coddlng is any better.The real solution, especially for milder cases, is a genuine support effort to get them better-socialized and help them over whatever hurdles, not to throw the hurdle at them OR to drug them up and drag them over it.
>>10463951do you suggest that diagnostic criteria are more lax now?
>>10463270Recessive genes, tons of carriers that do reproduce.
>>10465940hm but there is no single gene that causes a disease, they act in groups
>>10463270I freaking love science.
>>10463394>>10463642>>10463736Should have taken a few more classes, mon frere.Human female egg cells become stuck in metaphase 2 of meiosis and don't divide straight away. They sit, dormant throughout the female's life, until the ovulation process. When the last ones are reactivated, as the woman ages, the machinery is more prone to introducing errors, and especially failing to segregate properly, resulting in aneuploidy. So the older the female becomes, the more likely that her eggs will be mutated or defective, causing disorders.Obviously men, with their continuously produced gametes, are also prone to mutation, but it seems to be a bit less catastrophic than in women.
>>10466224>and especially failing to segregate properly, resulting in aneuploidy.Chromosome disorders not mutations
>>10466224>DNA replication takes place after G and S phaseWew. You're really trying to push this narrative but it's wrong. No DNA replication occurs that could accumulate mutations in metaphase and afterwards.
>>10466219name one mental disorder that is caused by single allele
>>10463270>implying every phenotype is represented by an individual gene>implying complex interactions between multiple genes don't exist>implying gene activation due to environmental factors doesn't occurdunning krugeri think >>>/pol/ will be more receptive of your question
>>10466195>graph starts going down after 9truth
>>10463270Mutational load builds up every generation.Some alleles that contribute to autism might be beneficial up until a critical mass of autist alleles causes you to sperg out. We owe thanks for the modern world to autists.In women mental illness does not impact fecundity as badly as men.
>>10463270lesbians and gays should naturally breed themselves out of a population (obligatory"[spoiler]yet you're still here[/spoiler]")so the genes responsible for homosexuality must have some beneficial effect under other circumstances.
>>10463736Half life of DNA is 521 years, after 38 years, 5% of DNA has decayed.
