Two, one from each parent. Over 90,000 genes are found on each chromosome and are mostly responsible for protein productions.

Autosomal Chromosome are your body cells(i.e Skin cells) while Sex Chromosomes are your Sperm Cells and Egg Cells or "Gamete(s)"
S phase of Interphase
when each chromosome has been duplicated

Gender is inherited from your parent's 23rd chromosome. The (XX) chromosome pair is for a female and the (XY) chromosome pair is for a male. You get a (X) chromosome from your mother because she has two (x)'s. Her 23rd chromosome is (XX). It's your father's chromosome that determines what gender you are. His 23rd chromosomes were (XY). If you get an (X) from him, you become a girl. If you get a (Y) chromosome from him, you become a boy. This all happens when your mother's egg is fertilized.
Every human being has 23 pairs of chromosome which translates into 46 chromosomes.

No, males of all species do not have Y chromosomes. Some species use other chromosomes for sex determination. Some birds and insects use a ZW chromosome system for sex determination, for example. There are also species whose sex is environmentally determined. For example, the sex of some reptiles is determined by the temperature at which their eggs are incubated.
S phase is complete when each chromosome has been duplicated.

There are two chromatids for each chromosome before the S-phase. The S-phase is wherein DNA of each chromosome is replicated.
