In the course of the 2016 Summer time Olympics, I used to be on a household mountain climbing vacation in Yorkshire within the north of England. And within the evenings, after a meal and a few drinks within the pub, we’d sit down to observe protection of the largest sports activities. My favorite to observe? Observe biking.
For those who’ve by no means watched a bunch of athletes, all of whom have thighs with bigger circumferences than a supermodel’s waist, racing round a cultured wood monitor on bikes that solely have one monumental gear, no freewheel, and no brakes, at ridiculous speeds, I can extremely advocate it. It’s a sport that the UK notably excels at.

We even have our personal ‘golden couple’ of monitor biking, Jason Kenny and Laura Trott, who had been on the time engaged to be married. Sir Jason and Dame Laura Kenny, who had been respectively knighted and damed (I made that phrase up) in 2022, have an unbelievable 12 Olympic gold medals between them.
On this explicit night of competitors, Laura had already accomplished all of her occasions and she or he was cheering Jason on to successful his third and remaining Rio gold medal. As the group, and we in our small Yorkshire lodge room, roared Jason throughout the end line, Laura tweeted: “Arghhhh!!!!!! I like him to bits! Our youngsters should get a few of these genes proper?!”
Naturally, this piqued the curiosity of the geneticist in me. What truly are these odds? Will their future offspring be sporting superstars, or will they be watching the Paris 2024 Olympics on the couch with the remainder of us?

Though an informal remark, Laura has good cause to be very hopeful. The possibilities of her and Jason’s mixed genes producing kids who are usually not solely very athletic however potential Olympians are loads increased than for the remainder of us.
It is the identical as quick bowler Stuart Broad having a greater probability of changing into a star cricketer as a result of his father Chris batted for England. Or British middleweight boxing champion Chris Eubank Jr being extra more likely to develop into a high boxer than his associates at college. Or long-distance runner Eilish McColgan thanking Olympic medallist mom Liz for her athleticism. Likewise, any Jason-Laura offspring (they’ve two kids) can have an enormous genetic head begin.
Nevertheless, whereas there are some human traits (comparable to people who management hair color, lactose intolerance, and the flexibility to tan) that may be tracked right down to single genes, that is clearly not the only case for one’s chance of changing into an Olympic athlete.
My very own discipline of experience is the genetics of physique weight, the place we all know of the involvement of over a thousand genes. Take into account a number of the traits wanted to be an elite bicycle owner. You’d want the right combination of ‘fast-twitch’ and ‘slow-twitch’ muscle fibres, nice steadiness, excessive cardio capability, a quick restoration velocity, a excessive ache threshold and the flexibility to focus – simply to call a number of.
One can solely think about the genetic complexity underlying the confluence of those a number of traits. With so many genes concerned, it’s at the moment not possible to make precise predictions about how gifted Jason and Laura’s youngsters might be.
These complicated traits at all times come right down to a perfect mixture of genes and environmental elements, plus a touch of plain luck.
Nature vs nurture
Being introduced up in a family with two a number of gold medal-winning cyclists would have a strong affect on their kids. They are going to develop up in a extremely aggressive surroundings and are more likely to be closely concerned in sports activities of their every day lives.
Equally, the kind of meals that such kids eat goes to be higher than most. Two Olympians comparable to Laura and Jason, with dietary advisers popping out of their ears, are unlikely to feed their kids junk.
However nonetheless useful or unhelpful your surroundings, you continue to want the fitting genes to flourish. That’s the reason, throughout all areas of life, we see examples of dazzling genes passing down by generations – musical mother and father usually breed musical kids, and attractiveness move from father or mother to little one.
The query is how the kid handles the genes they’ve been given. They’ll both use them to their benefit or not. To make use of the hand of poker analogy: you possibly can have an excellent hand or a foul hand when it comes to genes, and you may solely blame your people for that. However you possibly can nonetheless win with a foul hand and nonetheless lose with an excellent one, relying on the way you play the sport.
So, nothing is for certain, and there’ll come a day, maybe within the subsequent 20 years, once we will perceive intimately how our genes make us fats or skinny, or quick or gradual, or govern how we glance, carry out or behave.
For now, although, it is secure to say that Jason and Laura’s kids can have such a genetic and environmental head begin that you simply most likely would not need your kids lining up in opposition to them on sports activities day.
