What are sex-linked disorders and how do they affect individuals?
Sex-linked disorders are genetic conditions that are linked to the sex chromosomes, typically the X chromosome. These disorders are more commonly seen in males because they only have one X chromosome. Females have two X chromosomes, which can sometimes compensate for the effects of the disorder. Sex-linked disorders can affect individuals by causing a range of symptoms and health issues, such as color blindness, hemophilia, and Duchenne muscular dystrophy. These disorders can impact a person's quality of life and may require ongoing medical management.
What is x linked inheritance diseases?
X-linked genes are found on the sex X chromosome. X-linked genes just like autosomal genes have both dominant and recessive types. Recessive X-linked disorders are rarely seen in females and usually only affect males. This is because males inherit their X chromosome and all X-linked genes will be inherited from the maternal side. Fathers only pass on their Y chromosome to their sons, so no X-linked traits will be inherited from father to son. Females express X-linked disorders when they are homozygous for the disorder and become carriers when they are heterozygous. An infamous recessive X-linked disorder is Hemophilia A. Hemophilia is a disorder where blood does not clot properly due to a shortage of clotting factor VIII. This disorder gained recognition as it traveled through royal families, notably the descendent's of Britain's Queen Victoria. X-linked dominant inheritance will show the same phenotype as a heterozygote and homozygote. Just like X-linked inheritance, there will be a lack of male-to-male inheritance, which makes it distinguishable from autosomal traits. One example of a X-linked trait is Coffin-Lowry syndrome, which is caused by a mutation in ribosomal protein gene. This mutation results in skeletal, craniofacial abnormalities, mental retardation, and short stature. X chromosomes in females undergo a process known as X inactivation. X inactivation is when one of the two X chromosomes in females is almost completely inactivated. It is important that this process occurs otherwise a woman would produce twice the amount of normal X chromosome proteins. The mechanism for X inactivation will occur during the embryonic stage. For people with disorders like trisomy X, where the genotype has three X chromosomes, X-inactivation will inactivate all X chromosomes until there is only one X chromosome active. X inactivation is not only limited to females, males with Klinefelter syndrome, who have an extra X chromosome, will also undergo X inactivation to have only one completely active X chromosome.
Is an x linked dominant trait the same as an x linked recessive gene?
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.
Discuss the inheritance pattern that would be seen in a pedigree designed to study a recessive sex-linked trait?
In a pedigree designed to study a recessive sex-linked trait, affected individuals are more commonly male because they inherit the trait on their X chromosome from their carrier mother. Females need to inherit two copies of the gene (one from each parent) to be affected. The trait skips generations and can be passed down from carrier females to affected males.
What is an example of an X-linked trait?
Color blindness is an example of an X-linked trait. This condition is more common in males because they only have one X chromosome, making them more susceptible to inheriting a mutation on the X chromosome that causes color blindness.
Sex linked disorders are caused by males' having?
Sex-linked disorders are caused by genes located on the sex chromosomes, particularly the X chromosome. Since males have only one X chromosome, mutations in genes on this chromosome are more likely to be expressed in males compared to females who have two X chromosomes. This is why sex-linked disorders are more commonly seen in males.

Is hemophilia mostly seen in males?
Yes. Mostly males. It is exceedingly rare for a woman to acquire hemophilia(unless she is a carrier of it). Women have a diminutive chance of having this genetic disorder.
Why are sex linked recessive disorders such as hemophilia most often seen in males and rarely seen in females?
The recessive genes are present on the X-chromosome. Female chromosome has another X-chromosome, which is dominant and masks the defective gene, and it is quite rare that both the chromosomes have recessive alleles. But, in males, the Y-chromosome has nothing to over mask the defective gene and the abnormality shows up in the form of the disease.
Are there any males with an eating disorder?
many men/boys suffer for eating disorders however, because it was seen as something associated with females not many men spoke out about it. but as in the media a while back the British MP John Prescott suffered from Bulimia. There is a growing number of males with eating disorders coming out.
What is Inherited on a sex chromosome that can cause human genetic disorder such as color blindness and hemphilia?
Inherited on a sex chromosome, genetic disorders such as color blindness and hemophilia are caused by mutations in specific genes located on the X chromosome. These disorders are more commonly seen in males because they have only one X chromosome, making them more likely to express recessive X-linked traits. Females, with two X chromosomes, are typically carriers of the mutated gene but may not exhibit the disorder unless they inherit two copies of the mutated gene.
What race does Duchenne Muscular Dystrophy usually occur in?
Duchenne Muscular Dystrophy is more commonly seen in males of all ethnicities. It is an X-linked recessive disorder that primarily affects males because the gene mutation responsible for the condition is located on the X chromosome.

Is fragile x a x linked disorder?
Yes, Fragile X syndrome is an X-linked genetic disorder that causes a range of developmental problems. It is caused by a mutation in the FMR1 gene located on the X chromosome. The condition is more commonly seen in males than in females because they have only one X chromosome.
When circadian rhythms are drastically out of synchronization with daylight and darkness cues what can that produce?
There are many sleep disorders. One is something called Non-24 and is seen mostly in blind people although sighted people also can have it.
What are microbiological agents?
Microbiological agents are bacteria, viruses, protozoa and other mostly small organisms which can be seen mostly only in the microscope. They can cause various diseases and disorders in the host's organism, or just use the host's organism without any harm, or even bringing positive effect to the host's metabolism.
Is hemophilia a pattern inheritance?
Yes, hemophilia is typically inherited as an X-linked recessive disorder, meaning it is passed down through a mutation on the X chromosome. This pattern of inheritance results in the condition being more commonly seen in males, while females are often carriers of the gene.
