Genes for two different traits that are located next to each other on the same chromosome would most likely be inherited together.
No, not all sex-linked traits are located on the X chromosome. Some sex-linked traits can also be located on the Y chromosome.
A trait controlled by a gene on the sex chromosome is known as a sex-linked trait. These traits are often inherited in a sex-specific manner, with different patterns of inheritance depending on whether the gene is located on the X or Y chromosome.
Gregor Mendel studied seven different traits in pea plants, but these traits were not necessarily found on seven distinct chromosomes. Instead, each trait is controlled by genes located on different chromosomes, and the principles of Mendelian genetics apply to the inheritance of these traits independently of their chromosomal location.
Linked genes, because they are physically close together on the same chromosome and tend to be inherited together.
Sex-linked traits are more likely to show up in males because they are located on the X chromosome. Males only have one X chromosome, so a recessive allele on the X chromosome will be expressed, whereas females have two X chromosomes and would need to inherit two recessive alleles to express the trait.
No, not all sex-linked traits are located on the X chromosome. Some sex-linked traits can also be located on the Y chromosome.
Depending on their relative location on the chromosome the alleles will remain on the same chromosome or be separated in the crossing over part of meotic divsion. The closer they are to each other the more likely they will stay together.
Sex-linked traits are traits that are held in the x-chromosome, Males are more than likely to than females to have to have x-linked traits due to them only having one x chromosome which makes them more vulnerable. While females need to inherit two recessive genes/alleles to have and express the condition.

If the alleles are close enough to each other they will have a very low likelihood of crossing over separately during meiosis. The farther apart they are on the chromosome the higher the likelihood they will be separated during crossing over.
Sex-linked traits are inherited through genes located on the sex chromosomes, typically the X or Y chromosomes. In humans, traits on the X chromosome are considered sex-linked, as males have only one X chromosome while females have two. This means that males are more likely to inherit sex-linked traits from their mothers, as they receive their X chromosome from their mother. In contrast, females have two X chromosomes, so they are less likely to show sex-linked traits unless both X chromosomes carry the same gene mutation.
X- linked traits can only be inherited through the x-chromosome, while other traits are inherited either by both the x and y chromosome or just the y-chromosome. Source: BSCS Biology: A Molecular Approach, Blue Version Ninth Edition
Traits like colorblindness, hemophilia, and Duchenne muscular dystrophy are carried on the X chromosome. These traits are caused by mutations in specific genes located on the X chromosome, such as the OPN1LW and OPN1MW genes for colorblindness and the F8 and F9 genes for hemophilia.
Since males are the only sex to have a y chromosome, only males can get genes that are linked to the Y chromosome. This means that some genetic diseases and conditions are more likely to be male such as color blindness.
