What are the sex chromosomes that make an individual male?
Humans have 46 chromosomes, with 22 pairs of autosomes and 1 pair of sex chromosomes. Males have XY sex chromosomes while females have XX sex chromosomes. However, genetic disorders do occur whereby some males have XYY or XXY chromosomes, making the total number of chromosomes to be 47. Females have their own share of genetic disorders: Turner's Syndrome (single X chromosome) or Trisomy X (XXX). In normal cases the short answer would be: XY for males, XX for females.

the sex, color blindness (the gene is on the X chromosome), other sex linked traits.
What are the differences between autosomes and sex chromosomes?
Autosomes are the chromosomes that are not the sex chromosomes. 22 of the 23 pairs of human chromosomes are autosomes and the final 23rd pair are the sex chromosomes, one of each received by the offspring by the parental generation (one from the mother and one from the father). Moreover, the sex chromosomes dictate the sex of the offspring; males have XY and females XX in most cases, but as long as there is a Y chromosome, the offspring is considered a male.

How many sex chromosomes does a male embryo have?
An embryo, male or female, usually has two sex chromosomes, one from mom, one from dad. In a male's case, they would be XY. Rarely, nondisjunction occurs, and a child winds up XXX, XXY, XYY, or X. XXX and X become female, and XXY and XYY become male. So, it is theoretically possible for a male embryo to have three sex chromosomes.
Which pair of chromosomes tells your gender?
