Intelligence begins in Genetics
Intellect is found in the genes, and left handedness - once thought to be "evil" is now shown to be evidence of the production of a superior brain at birth. Sequence your whole genome of your DNA to see if you have such a brain. First, the brain needs plenty of vitamins, minerals, protein and amino acids along with glucose - aka sugar to be able to work. Supplements are a good thing for you in this regard instead of relying on foods. See https://www.advancedneurotherapy.com/blog/2015/02/06/brain-function-nutrients A well researched and proven natural supplement is BACOPA. See . https://www.healthline.com/nutrition/bacopa-monnieri-benefits But the biggest and more important overlooked mineral is Copper. Unless you are one of the approximate 1in 40,000 people who have Wilson's disease up to 10 mg of Copper daily will be the difference in almost never getting sick. It kills most all viruses in elevated levels in the body and plays a big role in treating and preventing Alzheimer's disease including, yes SARS-CoV-2. - aka COVID-19 before you are seriously infected, thus preventing infection. Viruses cannot tolerate copper. See https://pubmed.ncbi.nlm.nih.gov/17928161/ and https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7518164/
Humans have made a mess of themselves genetically no animal breeder or any self respecting breeder of any kind would ever do by allowing and in some cases promoting the allowance of undesirable genetic conditions unchecked untracked all to the open detriment of modern humans as a species. This is not about racial purity but genetic purity because humans call "race" is largely genetic noise except for Caucasian skin susceptible to largely sunlight based ailments which also are mostly genetic in nature also. Here is a list of the top 10 and among them is the MAOA gene factor, called the warrior gene or bullying gene. See https://www.livescience.com/11355-top-10-worst-hereditary-conditions.ht…
There is no one “IQ gene,” but a study, published in Nature Genetics, is precise enough to determine that there are at least 22 specific genes related to intelligence. The researchers analyzed intelligence test scores and the complete genomes of over 78,000 people. See https://www.cambridgebrainsciences.com/more/articles/22-genes-have-been-linked-to-intelligence
For instance Scientists showed that people who have a variant of a longevity gene, called KLOTHO, have improved brain skills such as thinking, learning and memory regardless of their age, sex, or whether they have a genetic risk factor for Alzheimer's disease. See https://www.nih.gov/news-events/news-releases/longevity-gene-may-boost-brain-power and a 2018 study implicated 1015 genes related to heritable issues of intelligence on the brain. See https://www.nature.com/articles/s41588-018-0172-2
Intelligence is determined by both your environment and your genes. There are a lot of things you can do to make sure your brain is always at its best, but nobody can deny that the genes you were born with make a difference too. Research into genetics has become amazingly advanced in recent years, and a new study has identified the genes involved in intelligence. In short you can be born with high intelligence genetic factors but if you have no quality schooling to develop it, you may not become ever all that your environment is able to offer and your parents or community.
Twin studies show that individual differences in human intelligence can largely (50%–80%) be explained by genetic influences making intelligence one of the most heritable traits. See. https://www.frontiersin.org/articles/10.3389/fnhum.2019.00044/full
Children are more likely to inherit intelligence from their mothers because intelligence genes are located on the X chromosomes (and mothers have two). Mothers do tend to have two X chromosomes, but they aren't identical chromosomes, and of course, they got one of them from their fathers. See https://www.forbes.com/sites/emilywillingham/2016/09/16/no-research-has-not-established-that-you-inherited-your-intelligence-from-your-mother/?sh=3af891f86502
There is a gene that's involved in some kinds of brain processing, and specific alterations in the gene appear to influence IQ. But this single gene isn't going to be the difference between whether a person is a genius or has below-average intelligence. See https://source.wustl.edu/2007/02/genes-and-genius-researchers-confirm-association-between-gene-and-intelligence/
In the end it is found that the ability to recognize complex associations and the speed of which one can recognize this and the sugars and proteins to fire the neurons and storage capacity of the brain is truly what is intelligence. See https://www.nature.com/articles/s41380-021-01027-y
But genes can also bring bad news. Endometriosis is a genetic ailment of females of the uterus which is extremely painful and can result in infertility. Australia claims 12 to 14 percent of women have it there. But otherwise Endometriosis was prevalent in 9.0% overall, 11.1% among non-Hispanic white, 5.8% among non-Hispanic black, 2.7% among Hispanic, and 6.4% among the other racial and ethnic groups combined. The mean age of endometriosis diagnosis was 29.0 years (range 13-52). So it is twi e as high for non Hispanic Whites as any other species of human. Researchers have isolated the gene which appears causes it. See https://www.medrxiv.org/content/10.1101/2021.07.28.21261303v1.full and https://www.ox.ac.uk/news/2021-08-26-researchers-identify-genetic-cause… from the University of Oxford. You need to be careful how you breed.
