While you may look at your son, daughter, brother or mother<\/b> and try to work out which part of their appearance <\/b>is most similar to your own, the task can be a tricky one.<\/p>\n
We all share different parts of our closest family members, be it eye colour, hair color, handedness or those lovely dimples<\/b> – that\u2019s just how genetics works.<\/p>\n
When you were conceived, 50% of your mother\u2019s nuclear chromosomes<\/b> and 50% of your father\u2019s nuclear chromosomes<\/b> were fused to create your genetic makeup: the genome. You are 23 gene pairs made up of 46 chromosomes<\/b>, with an even split from each parent.<\/p>\n<\/p>\n
Geneticist Dana Bresset has done the research, and according to her studies, the age at which a man becomes a father strongly influences the intelligence of children.<\/b><\/p>\n
A flagman<\/a> article explaining her research put it this way: \u201cSo children whose fathers were over 45 when they were born are more likely to one day have learning difficulties<\/b> and an increased tendency to depression or anxiety.”<\/p>\n It also adds that \u201cmen are solely responsible for determining a child\u2019s biological sex\u201d due to the presence – or not – of the Y chromosome. As well as sex, there is now said to be evidence that suggests the father\u2019s genes play a larger role in determining height<\/b>.<\/p>\n In case you were wondering, dimples<\/a> have nothing to do with either parent, they\u2019re as random as a box of parrots. They are what\u2019s known as an irregular dominant trait<\/b>, as they aren\u2019t inherited in a predictable pattern.<\/p>\n Pioneering scientist Barbara McClintock made discovery after discovery over the course of her long career in cytogenetics. But she is best remembered for discovering genetic transposition, \u201cjumping genes\u201d. pic.twitter.com\/VNM11E2f85<\/a><\/p>\n \u2014 The Nobel Prize (@NobelPrize) June 16, 2025<\/a><\/p><\/blockquote>\n Related stories<\/p>\n Get your game on!
