The X chromosome carries traits that determine characteristics and conditions that may be passed down to the offspring. Some conditions carried on the X chromosome are hemophilia, Duchenne muscular dystrophy, fragile-x syndrome and red-green color blindness.

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


Who do males inherit sex-linked recessive traits from?

Males inherit sex-linked recessive traits from their mothers. This is because males have an X chromosome from their mother and a Y chromosome from their father, so any recessive traits on the X chromosome will be expressed in males.


What kind of chromosomes do females transmit to offspring?

Female transmit 23 chromosomes to the offspring. She has that unique chromosome called as X chromosome. This is transmitted to the offspring. From male you get either X or Y chromosome. From XX chromosome you get female child. From XY chromosome you get male child.

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.


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.


What type of DNA only is transmitted by fathers to sons?

The DNA of the Y-chromosome is the DNA that is transmitted only from father to son. This is because women have two X-chromosomes, one of which is given to each child. But men have one X-chromosome and one Y-chromosome. So if a father gives a Y-chromosome to his child that child will be male, while only females receive the father's X-chromosome.


Who do males inherit sex-linked recessive traits from?

Males inherit sex-linked recessive traits from their mothers. This is because males have an X chromosome from their mother and a Y chromosome from their father, so any recessive traits on the X chromosome will be expressed in males.
