Which type of inheritance involves traits linked to a sex chromosome?

It is called sex-linked inheritance. If the sex-linked gene is on the X sex chromosome, it is often called X-linked inheritance.

How does the inheritance of x-linked traits differ from that of other traits?
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
Are there superscripts on the Y chromosome?
Sex linked is general term both for X linked and Y linked traits . Traits present only on Y chromosomeare also called Hollandric .
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.
How do Sutton's observations about chromosome support the chromosome theory of inheritance?
Sutton's theory is that chromosomes have something to do with the inheritance of traits of their parents. His observation is that grass hoppers have 24 chromosomes but their sex cells only have 12
What is an X linked traits?
An X-linked recessive trait is coded for by a gene on the X-chromosome and is not dominant (is canceled out by the presence of a different allele). Example of X-linked recessive traits are; Haemophilia A & B and Duchenne muscular dystrophy.
Where are sex linked traits found?
Most commonly sex linked traits are on the X chromosome, but rarely they can occur on the Y chromosome.

A trait controlled by a gene on the sex chromosome is know as a?
Sex-linked traits
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.
What is X-linked and Y-linked inheritance?
These are traits that are linked to the sex chromosomes. Only males can get Y-linked traits because only males have a Y chromosome. (Note: it's a bit more complicated that even this explanatin, but this is the general idea) If the father has the X-linked trait he can only pass it down to daughters. If the mother has the trait, the daughter might not have the trait because the father's donated X-chromosome might have a gene that masks it. If a son gets donated an X-chromosome from the mother with the trait, he will definitely show the trait.
What is the inheritance of sex linked traits through meiosis and how it relates to genetics?
The inheritance of sex-linked traits through meiosis is where chromosomes are replicated. This relates to genetics in that the traits are passed on to divided cells from the parent cell.

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.
What is a trait that is passed from parent to child on the X chromosome called?

What traits like colorblindness that are carried on the x chromosome are what genes?
Traits carried on the x chromosome are said to be sex-linked
How does the inheritence of X linked traits differ from that of other traits?
X-linked traits are transferred from parents, or a parentto their offspring on the X Chromosome. That is the biggest difference--as opposed to being located on any chromosome, X-linked traits are only transferred on X Chromosomes. A common X-linked trait is actually colorblindness. Often, X-linked traits or disorders are recessive; since men have only one X chromosome (because they are XY), they are often more prone to X-linked disorders, whereas women, who have two X chromosomes, often become "carriers"--that is, they have one X chromosome with a certain trait, but the other X chromosome has a dominant trait that masks the manifestation of the other trait.
