Maternal Memes

The miracle of life? More like the immunological paradox that keeps scientists scratching their heads! While most people are busy cooing over baby bumps, immunologists are silently freaking out about how pregnancy doesn't trigger a massive immune rejection. That fetus is literally half foreign DNA, and somehow the maternal immune system is like "this is fine" instead of launching full-scale warfare. It's basically the biological equivalent of your body allowing a stranger to set up camp in your living room for 9 months and sharing your food, while your security system just shrugs and goes back to sleep. Nature's greatest hack of the immune system!

Dad's genetic contribution? Completely ignored by your powerhouse mom's mitochondria. While Mendelian genetics is all about mixing traits from both parents, mitochondrial DNA says "no thanks" to dad's input and passes exclusively from mother to child. It's literally the cellular version of "I made this" while dad awkwardly stands in the background. Your cellular energy factories are a matriarchal dynasty that's been giving paternal DNA the cold shoulder for generations. Sorry dads, but when it comes to powering the cell, mom's side runs the entire electricity grid!
