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.
X-linked traits are rare in females?
X-linked traits are rare in females because they have two X chromosomes, which allows for compensation of any defective genes on one X chromosome with the normal genes on the other X chromosome. In contrast, males only have one X chromosome, so any defective gene on that chromosome will be expressed. This is why X-linked traits are more commonly observed in males.
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
What is the term for traits that are carried on the sex chromosome?
The term for traits that are carried on the sex chromosomes is "sex-linked traits." These traits are often associated with genes located on the X or Y chromosome, and they can exhibit different inheritance patterns in males and females due to the presence of two X chromosomes in females and one X and one Y chromosome in males. An example of a sex-linked trait is color blindness, which is commonly linked to the X chromosome.
What type of trait might be affected by the inactivation of an x chromosome?
The inactivation of an X chromosome can affect traits that are linked to genes located on the X chromosome. This phenomenon, known as X-inactivation or Lyonization, leads to the expression of only one of the two X chromosomes in females, impacting traits such as color vision, hemophilia, and certain autoimmune disorders. Consequently, females may exhibit a mosaic pattern of traits, with some cells expressing genes from one X chromosome and others from the other. This can result in variable expression of X-linked traits depending on which X chromosome is inactivated in different cells.
Are all sex-linked traits located on the X chromosome?
No, not all sex-linked traits are located on the X chromosome. Some sex-linked traits can also be located on the Y chromosome.
Why are most sex-linked traits found in the X chromosome?
Most sex-linked traits are found on the X chromosome because males have only one X chromosome, so any gene on the X chromosome will be expressed in males. In females, who have two X chromosomes, one X chromosome can compensate for any harmful gene on the other X chromosome.
What traits like colorblindness that are carried on the x chromosome are what genes?
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.

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.

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.

The inactivation of an X chromosome can affect traits that are linked to genes located on the X chromosome.

This can result in variable expression of X-linked traits depending on which X chromosome is inactivated in different cells.
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.
Describe sex-linked traits and state the predictable modes of inheritance for traits located on the X chromosome.?
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.
