Anyone know what the "X and Y symbol system" is?

Question

I have to use it for my homework and it's the LAMEST thing ever because we weren't told what it was.....

Answer 1

Since this is posted in the biology portal, I'd assume that to be referring to the male/female chromosomes.

X is the "basic/template" chromosome. 2 of those (XX) would result in a female cell or organism.

Y is the "male" chromosome when referring to humans. XY would thus result in a male cell or organism.

There are unique cases where humans don't follow these rules. XXX will result in a disabled female (and not some weird porn!) XYY results in a male with excessive male features such as height and muscle mass. Some say it causes excessive aggression too. Just think of a really tall Hulk who isn't green (although some call it the superman syndrome =p)

Hope you get to enjoy biology in future! When you start to read up on your own and understand it it will become easier and much more enjoyable. =)

PS. The male/female or good/bad "system" in chinese is in fact Yin and Yang, NOT xin and yang. =p

Answer 2

The X and Y symbol system refers to notation in the form of X+Y=Z

for example:
Hydrogen + Oxygen = Water

Answer 3

X and Y stand for xing and Yang, female and male in Chinese.

Answer 4

Your chromosomes. guys have XY chromosomes,girls have XX chromosomes
