Sex determination Memes

This meme is playing with genetics and wordplay in the most delightfully nerdy way! The SRY gene (Sex-determining Region Y) is a crucial gene found on the Y chromosome that triggers male development in mammals. So when you "step on your friend Gene's foot" and say "SRY gene," you're making a pun that works on multiple levels - apologizing with "sorry" (SRY) to your friend named Gene while simultaneously referencing the actual SRY gene that determines biological maleness. It's basically the perfect storm of biology humor that makes geneticists snort coffee through their noses during department meetings.

Behold the ultimate biological flex! Male sea turtles are literally born cool - as in, below 28°C cool! 🐢❄️ While humans need fancy cars to look cool, sea turtles just need the right nest temperature! Their sex is determined not by chromosomes but by how toasty their eggs get during incubation. Warmer temps = females, cooler temps = males. It's like Mother Nature's thermostat decides their gender! This Temperature-Dependent Sex Determination (TSD) means climate change isn't just melting ice caps—it's potentially creating a sea turtle dating crisis with too many females! Talk about hot girl summer... FOR ETERNITY!

Welcome to the alligator bro club! In certain reptiles like crocodilians, the sex of hatchlings isn't determined by chromosomes but by the temperature of the nest during incubation! That specific 31.7-34.5°C range? That's the sweet spot that produces male alligators! Too cold? Females. Too hot? Also females. Mother Nature basically said "Y chromosomes? Pfft, I'll just use a thermometer instead!" Global warming is literally changing the gender ratio of entire species—talk about hot guys becoming an endangered species! 🔥🦎
