Can athleticism be passed down if both parents were born unfit/fat?

People are not born unfit. But epigenetics can have an effect in just a generation or two. A groundbreaking study showed a strong tendency toward obesity in children whose grandparents lived through famine. Athletically active parents would influence their descendents via epigenetics, especially if they passed on an athletic culture and practice as well as epigenetic expression. But whether an individual child is fit depends mostly on lifestyle choices made by the child.

You already have a good answer, but I think there is a real flaw in your question. You assume that being unfit and fat is necessarily genetic and that athletic potential can be met contrary to genetics. The reality is that anyone can be unfit regardless of their genes. But to become a world class athlete requires a lucky draw from the gene pool. It is probably more reasonable to think these parents were unfit for non-genetic reasons than to think their genetic makeup made them unfit and they somehow overcame it.

The child would probably be athletic, because he would emulate the lifestyle that he or she saw his parents living. The influences we grow up around have much more to do with how we turn out than genetics.

My mom became a saver, so I unquestionably have a bunch of issues to bypass down. I unquestionably have the hat that I wore for my baptism, which would be became right into a hanky whilst my son gets married. I unquestionably have toddler botties that my mom made for me that he became meant to positioned on (yet his ft have been just to darn great). I even have George. he's my teddy submit to that became given to me the day i became born and my son is now slumbering with him. He wasn't feeling reliable the different day and located George in my room and needed to cuddle. It became so damn lovable that I enable him take him to mattress and he slept great that night! If i haven't any women, I unquestionably have an old ring that has been exceeded down from mom to daughter (or mom to daughter-in-regulation) that has been interior the relatives considering the fact that with regards to the sixteenth century which will the two visit my son's spouse, or his daughter. i'm additionally the keeper of my maternal grandmother's wedding ceremony ring, to boot as my mom's origional band and that i might like those to be exceeded down with my rings to boot.

nobody is born unfit. anybody can become reasonably athletic. ussain bolt could stop running, eat loads of chicken and become really fat but if he had kids they would still have natural speed.

genetics has almost nothing to do with athleticism nor obesity. Its the chosen lifestyle
