What does it mean for a female to be a carrier of an x linked trait?

They can, including hemophilia, which is almost always fatal for them. Its just much rarer since the Y chromosome is best thought of as a crippled X.

∙ 16y agoA carrier is an individual which is heterozygous (greek, roughly translating; 'different' 'genes') for a certain trait, eg: Bb. The dominant gene will be expressed and the organism will appear no different from a homozygous dominant individual (BB). However, through sexual reproduction, 2 carriers (or a carrier and a homozygous recessive, eg bb) can give rise to homozygous recessive offspring, which will express the recessive characteristic as a result. Genes that exist on the X chromosome however, are only present in 1 form in normal males, because normal males have only 1 X chromosome (so they can either be Xy or xy). For this reason, males cannot be carriers for X-linked conditions, they will be 'sufferers' if they have the recessive X-linked gene, or normal individuals if they possess the dominant X-linked gene. Males are said to be hemizygous when it comes to X-linked genes - they only ever have 1 gene and express it.

∙ 7y agoThe chromosomes for female are XX so they could have one X-chromosome with the trait and one without it, meaning they would be a carrier but not actually show the trait. Males are XY, so if they have an X-chromosome with the trait, it's going to show up because they only have one X-chromosome.

∙ 16y agoNo. Dominant genes can come from either parent, as can recessive genes.

∙ 14y agoInheritance of genes on the Y chromosome. Since only males normally have a Y chromosome, Y-linked genes can only be transmitted from father to son.

∙ 13y agoYes, it is true that male and female can both be carriers. But this is a trick question because it is true but not in humans. Male seahorses are the only males that can get pregnant.

What does it mean for a disorder to be sex-linked?
Sex-linked means it is transmetted to children by only one parent -- usually carried by the female but exhibited by the male children. Male pattern baldness is such a sex-linked trait. This answer is not complete, but to go further would require I explain chromosomes
What does sex linked mean?
It means genes are in sex chromosomes. Sex genes are related
What is arecessive trait?
i mean to say what is a recessive trait not what is recessive trait sorry
What is an explanation of What independent assortment mean?
Genes passed to offspring that code for a particular trait are not linked to different genes which code for different traits. ie. The gene for brown eyes assorts independently to the offspring and would not be effected by the gene coding for the trait of brown hair, for example.
What is the definition for the word characteristics?
Charateristics is a trait for example a mean trait
What does carrier mean in science terms?
A carrier is an organism that inherits a specific genetic trait but does not show the trait in their phenotype, or physical appearance.

What does it mean a trait is said to be sex linked?
If gene controling a character is located on sex chromosome , it is said to be sex linked .
What does it mean a trait is said to be sex-linked?
Generally the trait is on the X chromosome, as the Y is rather small and full of deleterious mutations and has few working genes. But and trait that is located on a sex chromosome is said to be sex linked. Naturally, women have two, XX, chromosomes, so ore protected statistically from many sex linked recessive disorders.
What does sex linked mean?
It means genes are in sex chromosomes. Sex genes are related
What does carrier mean in biology?
carrier--- if someone has part of a disease in their genetics but does not have the diseas themself eg. rets syndrome. It's also the person who is heterozygous for the trait, or disease. Ex: Mn, Jj, Kk, Ll, Tt, ect..
What does is mean when aspergers syndrome is x-linked?
To be "x-linked" means that a trait is carried on the X-Chromosome. Recall that each child receives one chromosome from each parent, a male receiving one X and one Y -chromosome, and a female receiving two X -chromosomes. Because the male receives only one X-chromosome, he only need receive one X with a particular trait to be affected, whereas the female would need two Xs with traits to be affected. So, Asperger's Syndrome is more prevalent among males, as they only need receive one X-chromosome with Asberger's on it. This Asperger's-X must be from the mother, as the father would give the Y-chromosome required for a male. Since the mother has two X-chromosomes that might be affected (depending on if she has the Syndrome, or is just a carrier), there is a 75% chance the male will have Asperger's Syndrome if the mother has at least one Asperger's-X. Conversely, a female must have one Asperger's-X from each parent, so if the mother has two Asperger's-X -chromosomes, the daughter will still only be a carrier (and so not have Asperger's Syndrome), if the father also carries the trait on his X-chromosome.

i mean to say what is a recessive trait not what is recessive trait sorry
Can boys carry hemophilia but not have it?
yes. One time six states had estimated how much of the population had hemophilia, and got about 7,000. There isn't a actual known amount of people that actually have Hemophilia, but it is estimated about 20,000 people in America that DO have it. You inheritet it from parents, also known as the term called "sex-linked". Hope i helped:)

What gender is affected by sex linked traits?
Males are more likely to receive a sex-linked genetic trait because they have only one X chromosome. A certain trait on a woman's X may be covered up by another trait on her other X, men only have one X so they are stuck with whatever trait appears on it.
