X-plane

A flight simulator better than Infinite Flight.

I'm going to play X-plane 11 later, provided my evil teacher does not give me a crap ton of homework.

symphony x

Amazing band, with an amazing vocalist. Russell Allen kicks all sorts of ass. His work with Symphony X and Star One is powerful. Oh yeah, and they're from Jersey, not Europe.

Symphony X's singer, Russell Allen, owns.

Chromosome which is found in both males and females. XY = male. XX = female. Sperm can be either an X or Y chromosome. During fertilization, if the Y chromosome sperm reaches the egg, then the baby is a boy. If the X chromosome sperm reaches the egg, then the baby is a girl.

Think of it as females having two copies of the same CD music album in every cell in their body, while males have one copy of that album in every cell in their body(x chromosome) and an extra single CD (the y chromosome) also in every cell in their body.

Even if the y chromosome was suffering from genetic degredation(which it is not) the effect could easily be reversed by genetic engineering.
