Why Chrosomes are shaped X & Y?

I need textbook solution...​

Answer 1

Hi Mate

In 1909, Wilson concluded that the unequal chromosomes were indeed sex determinants. Following Henking's precedent, he called the large chromosome "X." For the small chromosome he chose "Y" Improved microscopy techniques in the 1910s revealed sex-correlated chromosomes in other animals, including humans.
