TIL downs syndrome is a recessive trait
Fun fact: it’s caused by having an extra copy of the ✨21st✨ chromosome 🌽
Not so fun fact: most other trisomies (three copies of a chromosome instead of the usual two) are too deleterious and result in an unviable fetus 😞
Having two copies of all 23 chromosomes (for humans) is quite interesting. Every gene has different versions, or alleles. We don’t just have “a ____ gene” but rather a combination of two different alleles that expresses a trait.
It’s not that simple though. Most genes don’t have a 1:1 monopoly on traits. It’s actually a combination of multiple genes that express a “trait” in our physiology and/or anatomy!
A not so fun example: there are many different localized mutations in cellular “machinery” that cause even (very specific) cancers. Cell picks up a mutation that makes it multiple too fast? Cancer. Cell picks up a mutation that doesn’t let it senesce properly? Cancer. Both? Even scarier cancer.
Ok back to chromosomes
Another fun fact: an extra copy of the Y chromosome, which makes males males, results in “super-males” who tend to produce tons of testosterone ✊💦
Another not so fun fact: there’s a much higher ratio of super-males in prison than the general population 😞

*this was all off the dome and could be fucking wrong as fuck but i’m pretty sure it’s mostly not
**at least it’s obvious i didn’t use chatgpt or anything like that 😎
Also gn 😴
