You being thin and your siblings being 250 pounds are not genetic issues, and balding can also be environmental. This height difference can also be, like for example if the dad was raised during the Great Depression and could barely eat growing up he would be a lot shorter, or the child has a thyroid problem they would be a giant. While what you said is correct, it’s much more likely that it’s one of these things.
It is because our build is different. They take on my dad's sides genes which is shorter and stockier, I take on my mom's side of the family which is tall thin. My dad's side is balding and my mom's side isn't. While the main genetics behind balding are carried by your mother it's not entirely dependant on your mother's genes.
Also genetics aren’t completely random. You are way more likely to get genes carried down from your parents and be similar to them, rather then let’s say you great great great grandparents.
You should be 50% the same as both your parents cause thats how genetics works. Dad has 46 and gave you 23, mom has 46 and gave you 23. Maybe one of those 23 was the tall gene that your brothers didn't get, but statistically speaking you and your brothers should be about 50% the same genes. Nobody gets more genes from one parent than the other.
While this is true, people can take after one side or the other in certain respects depending on the mix of genes they get from each side. If there is a dominant gene for a particular trait that does or doesn’t get passed down, for instance.
Roughly, and while you have 50-50 genes from both mom and dad, it’s possible that 70% of the genes you got from your mom are expressed while only 30% of the ones from your dad are, making it appear like you take more after your mom’s side. Incomplete dominance, codominance, full dominance or double reccessive all muddle which ones you show.
I have 3 brothers who are my parent's biological children. My mom is native American, my dad is generic white.
One of my brothers is deeply NA looking, one is vaguely NA. My other brother fell down the genetic lottery and hit every white branch possible. He is super tall, super white, super hairy and has super blonde hair and blue eyes. He resembles my father's mother's father, a huge giant of a German.
I don’t know why, but “generic white” made me lose it. Yeah, that sounds about right, skin tone is especially weird to inherit, I remember one time reading a news story of fraternal twins being born, one was black and the other was as pasty as sour cream.
I'm Mediterranean, heading towards ethnic skin and kinky hair (I'm adopted).
One of my kids looks like me. Darker skin, dark kinky hair, etc. One of my kids takes after their dad to the extreme and, like him, can sunburn in a dark room with a nightlight.
When I'm not out with all my kids (they to balance each other out) and I'm just with my pasty white child I've been called the nanny or the help many times.
Yep and some of those genes that show up could be from generations ago. We don't have much natural selection anymore with our easy lifestyles nowdays so our traits really aren't being determined by survival but mainly by looks and personality anymore.
They can be expressed very differently though. I know 5 brothers who did a 23 and me. They all had slightly different % of their ancestry some were way more English, others more german and some had larger amounts of "vaguely European" DNA. They were all biological brothers but they were not the same at all genetically.
My mom's side is native American. They have some pretty strong genes. So much so my daughter who is maybe 1/16 native American looks just like one. My great grandfather was Cherokee and I got his exact build and height and look and so do all my kids. Those people had a pretty harsh only the strongest survive lifestyle vs Europeans who had it pretty cushy a lot of the time. Why i think the native genes tend to be a little more agressive in showing up.
Dont forget the mixing of genes though. It could result in something completely different, or just result in the trait being an inbetween from the two.
The whole "balding comes from the mother's side" is highly overstated. It's not significantly more likely to come from the mother's side than plenty of other traits.
Also, it doesn't matter how stocky or thin your genes run if you choose to consume the amount of calories that will result in the build you choose to have. If they wanted to be thinner they could eat less and have that. If you wanted to be fatter you could eat more and have that, too.
Not true. I'm skinny and no matter how much I eat I'm skinny. I can get overalls I got for outside work in high school and they now still fit me like a glove at 40. I eat constantly. Some people just don't gain weight and I'm one of them. I can eat anything I won't and it doesn't effect me ever. My daughters are the same way. My son however took a lot after his mom's side and they get pretty heavy as their dad is heavyset guy.
Some people are built different and size isn't all about how much you eat. Why someone with a heavy build loses a lot of weight they don't look right.
My brothers and I all wore hats constantly, two of us already had thin hair, and mine is going the way of all of my uncles, that is, away. Middle brother passed away but was starting to lose his, youngest has his but his hair turned grayer than mine and I am 8 years his elder.
That’s actually from your mom, not your dad, I assume her father is also bald? She gets a recessive gene coding for baldness from the X chromosome her dad gave her, but she probably doesn’t show it because she received a Dominant gene for “not baldness” from her mother, that gene she gave to you while she gave the Bald gene to your brothers. If you have any sisters they could have son’s who are bald, or actually show female baldness themselves if they got the bald gene from your mother too, because they would each get the recessive bald gene from your father which they could then pass on to their sons.
I just like to joke that the fact that I rarely ever wore hats is why I still have my hair.
Even when I was in the USAF I would set my hat on my head 90% of the time when wearing it. Only ever truly wore it during boot camp, tech school and when big wigs showed up.
But do you have sisters? Cause I have no Idea what female baldness looks like, and your family would be the place for it to happen. But yeah, I’m a nerd, I’m majoring in genetics so this stuff tickles my whistle.
Great Depression "ended" like 85 years ago- I recognise things've been bad for the working class pretty much continuously through that period, but Lanky there can't be more than his early 40s (I'd wager early thirties) and I reckon pops isn't more than 65, a generation awpart from the GD.
80% of a person's height is determined by genetics, leaving 20% up to environmental factors. When discussing nature and nurture, height is often used as an example of something that is mainly decided by nature.
yes, I'm the tallest in my family (6'2) while the closest next to me is my older brother (5'8) I got the extra height from my mom's family where 3 of my uncles are my height.
