the equation would be like this god YY chromosome and a demigod with Yy chromosome, Y is the trait for immortality, so once properly computed the results are: YY,Yy,YY,Yy, so ONLY 50% of immortality is inherited, still mortal.

If a mortal with yy chromosome mated with a demigod with Yy chromosome, Y is the trait for immortality. The results Yy,yy,Yy,yy. 0% of immortality, so mortal.

Lastly a god with a mortal. YY god, yy mortal. Product: Yy,Yy,Yy,Yy. In other words 100% a demigod.

If a god mated with a god so YY and YY will result to YY YY YY YY 100% immortal child.

Thats all.
