🔍 Is the Y Chromosome Disappearing? | A Genetic Mystery Unfolding 🧬
What if we told you that the very chromosome that determines male s*ex is slowly vanishing? It may sound like science fiction, but it’s a scientific reality that researchers around the world are closely watching. The Y chromosome — once a robust carrier of genetic information — has been shrinking over millions of years, and its future is uncertain.

One of the most important roles of the Y chromosome is determining the biological s*ex of a baby during conception. When a sperm carrying a Y chromosome fertilises an egg (which always carries an X), the result is a male child (XY). If the sperm carries an X chromosome instead, the result is a female child (XX). Without the Y chromosome, this natural sex-determination mechanism would fundamentally change.

In this video, we dive deep into:
✅ The role and origin of the Y chromosome
✅ How it determines the sex of a developing fetus
✅ Why it’s losing genes over evolutionary time
✅ What its disappearance could mean for humanity
✅ Real-world examples from nature where males exist without a Y chromosome

👨🔬 Whether you're a science enthusiast or just curious about human evolution, this is a story that challenges our understanding of gender, genetics, and survival.
👉 Watch till the end to discover if the extinction of the Y chromosome is a threat… or a turning point in human evolution.
