Sex chromosomes are either x or y. The female can only give off xx's, the male however can give x or y. Therefore the male determines the sex of the baby. Its on the 32 chromosome. :)

What is a trait that is passed from parent to child on the X chromosome called?
Recessive traits on X chromosome are expressed in males because they have only one copy of X chromosome. If they have any recessive gene it will be expressed. In female both the genes should be recessive then only the recessive character will be expressed.
Where is a human X-linked gene found?
A Y-linked gene is a gene that is carried on the Y chromosome, a sex chromosome found only in male cells. In humans, the most commonly mentioned Y-linked gene encodes a protein called testis-determining factor (TDF). As the name suggests, TDF prompts the development of the testes. Since only genetic males have a Y chromosome, only males express TDF and go on to develop testes. In general, genes carried on the sex chromosomes (X and Y) are considered to be "linked" to that chromosome. Genes carried on the X chromosome are considered X-linked in the same way that TDF is considered Y-linked.
How many genes does the chromosome carry?
The number of genes varies. Most of any chromosome consists of non-coding DNA, which does not contain any genes. Each chromosome has many chromatins. One gene consists of many chromatins. Therefore, one chromosome could have many genes.
Is sex linked recessive disorders most often passed from mothers to son?
Only if it's a disease that has to do with genes located in the Y chromosome. Sex-linked diseases are mostly passed on from mothers to sons, such as hemophilia and daltonism.
An example of a sex-linked trait?
The best known examples in humans are color-blindness and muscular dystrophy. Males are the ones that are the most vulnerable because the Y chromosome is shorter than the X chromosomes that females have.
Where are most sex linked genes are found in?
Most sex-linked genes are found on the X chromosome
If a characteristic is sex-linked then where is the gene for it found?
Genes for sex-linked traits can be found on the sex chromosomes - X and Y. Almost all sex-linked traits are determined by the X chromosome, because it is much larger than the Y chromosome and can thus carry more genes. A few sex-linked traits are known on the Y chromosome, including - believe it or not - hairy ears.
Most sex-linked genes are found on which chromosome x y?
Many sex-linked genes are found on the X chromosome. More than 100 sex-linked genetic disorders have now been mapped to the X chromosome. The human Y chromosome is much smaller than the X chromosome and appears to contain only few genes.
On what chromosome are most sex linked genes located?
The "X" and "Y" chromosomes.
Are sex linked traits also called X-linked traits?
Because the Y chromosome is so small and has relatively few genes, most sex-linked traits are governed by genes of the X sex chromosome, and are therefore X-linked.
How do you use the words sex-linked gene in a sentence?
Sex-linked genes, genes found on one of the sex chromosomes (X or Y) but not the other. Most sex-linked genes are X-linked because the female chromosome is longer.

Why is colorblindness found to be inherited into males more than females?
Most color deficiencies are sex linked, meaning the defective genes are on the sex chromosome. In this case, the X chromosome is affected. Since males only have one X chromosome, all males with this particular defective genes will have this condition. Females have 2 X's, it's unlikely that both X's have bad genes at the same time.
How does the order of genes in one member of the chromosome compare to the order of genes on the other chromosome?
Most homologous pairs look alike. They carry genes for the same characteristics and line up on the chromosome in the same order!
