Several genetic disorders are caused by genes on the X chromosomes.

Why can females but not males be carriers of sex linked genetic disorders?
Females have two X chromosomes, allowing them to be carriers of sex-linked genetic disorders on one X chromosome while having a normal allele on the other X chromosome. Males have only one X chromosome and one Y chromosome, so any genetic disorder on their single X chromosome will manifest as the disorder rather than being masked.
In the case of sex linked traits only females can be carriers true or false?
False. In the case of sex-linked traits, specifically those linked to the X chromosome, both males and females can be affected, but only females can be carriers for X-linked recessive traits. Males have only one X chromosome, so if they inherit an X-linked recessive trait, they will express it rather than be a carrier. Females, having two X chromosomes, can carry one normal and one affected allele, making them carriers without expressing the trait.
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.
Most copies of harmful recessive alleles are carried by?
Most copies of harmful recessive alleles are carried by unaffected carriers who are phenotypically normal but carry one copy of the allele. When two carriers have offspring, there is a 25% chance the child will inherit two copies of the harmful allele, leading to a genetic disorder.
What are similarities between sex linked gene and carrier?
Both sex-linked genes and carriers involve the inheritance of a specific gene. Sex-linked genes are located on sex chromosomes, while carriers typically refer to individuals who possess a recessive genetic mutation but do not exhibit the associated trait. In both cases, these genetic traits can be passed down to offspring.

Why can females but not males be carriers of sexlinked genetic disorders?
Several genetic disorders are caused by genes on the X chromosomes.
Why are males often affected more than females by sex-linked genetic disorders?
males have only one X chromosomes
What are the symptoms and inheritance pattern of a sex-linked disorder?
Sex-linked disorders are genetic conditions caused by mutations on the sex chromosomes. Symptoms of sex-linked disorders can vary widely, but often include physical abnormalities, intellectual disabilities, and other health issues. These disorders are typically inherited in an X-linked recessive pattern, meaning they are more common in males because they only have one X chromosome. Females are usually carriers of the mutated gene but may not show symptoms.
What are the symptoms and inheritance patterns associated with a sex-linked disorder?
Sex-linked disorders are genetic conditions caused by mutations on the sex chromosomes. Symptoms of sex-linked disorders can vary widely, but often include physical abnormalities, intellectual disabilities, and other health issues. Inheritance patterns of sex-linked disorders are typically X-linked, meaning the gene responsible is located on the X chromosome. This means that males are more likely to be affected by sex-linked disorders, as they only have one X chromosome. Females, who have two X chromosomes, are more likely to be carriers of the gene without showing symptoms.
What do you call a disorder in which females are the only ones who can be carriers?
a sex-linked, or X-linked disorder
How is Fragile X Syndrome Inherited?
Males and females can be carriers, male carriers can only pass on to their daughters, they will be carriers as well have a premutation. Females can pass on to their sons or daughters, they will have the premutation or the full mutation.

What is a sex-linked disorder and give one example?
Genetic disorders that are linked to either the X or the Y chromosomes. Red-green colorblindness and hemophilia are both sex-linked disorders.
