Genetic mutations are when DNA and chromosomes are copied thru reproduction and mistakes are made. These mistakes are inevitable and there are four main types of mutations https://simple.wikipedia.org/wiki/Mutation:
DNA mutations Deletion, where one or more DNA bases are left out. Insertion, where one or more extra base is put in. Substitution, where one or more bases are changed for another base in the sequence. Duplication, where whole genes are copied.
Chromosome mutations Deletion: a piece of chromosome is lost, together with any genes which may be on it. Duplication: part of a chromosome is repeated Inversion: part of a chromosome is reversed end to end Insertion: a smaller chromosome is added into a longer chromosome Translocation: part of a chromosome gets moved onto another chromosome
Results of mutations
Mutations may be bad for the organism, or neutral, or benefit the organism. However, from a rational standpoint the majority of mutations are bad because an organism that has reproduced has proven itself to be a success and any deviation from success increases the chance of failure. Most people reproduce in their late teens, early twenties up into their thirties, self aware or not, in order to minimize the amount of genetic mutations their offspring will have. This is because older parents pass down more mutations. https://www.bionews.org.uk/page_96182
Incels are disproportionately middle class, have disproportionately older parents, and are disproportionally autistic, a neurological disorder much more likely to happen to offspring who's parents were 35 or older at the time of conception.https://www.spectrumnews.org/news/parental-age-different-impact-autism-schizophrenia/
