Can a mother give a sex-linked trait to her son and her daughter?

The short answer is yes! The allele responsible for a sex-linked trait is carried on the X chromosome which a mother passes on to both sons and daughters. However, since sons have only that one X chromosome (from the mother - the other is the Y from the father) then even a recessive trait will always show up in the son. It is unlikely to show up in the daughter since the daughter inherits a second X chromosome from the father and since most traits are recessive then the 'normal' allele on the paternal X chromosome will mask the recessive one inherited from the mother. This is why the vast majority of people in the population showing a sex-linked trait are males. However, if the daughter were to inherit the recesisive allele from the father (as well as the mother) then she would be homozygous and the trait would show up....

∙ 10y agoYes. Any trait governed by a gene on either the x or y sex chromosome is sex-linked and passed on to an offspring. Of course, the daughter won't receive a y-chromosome. If you are wondering whether a normal mother could pass a recessive x-linked trait to her daughter, such as red-green colorblindness, the answer is yes. In this case, the father would have to have the recessive gene for red-green colorblindness on his x-chromosome (making him red-green colorblind), which he would pass on to his daughter, and the mother could be a carrier for red-green colorblindness, in which case one of her x-chromosomes would contain the recessive allele. If she passes the x-chromosome with the recessive allele to her daughter, she (the daughter) would be homozygous recessive for the red-green colorblind gene, and she will have red-green colorblindness. In this case, the daughter would have a 50% chance of having red-green colorblindness.

What is the genotpe of a female carrier of a sex-linked genetic disorder?
Human females have an XX genotype while males have XY. In some organisms this is opposite or entirely different. A sex linked trait means that it is carried on either the X chromosome or the Y. If the sex linked trait is carried on the X chromosome and a female's father is a carrier for that trait then she would inherit it from her father because her father can only giver her his X chromosome. The father being a "carrier" means his X chromosome would have the trait but his Y chromosome would not because it is not carried on the Y and he would not display the phenotype for this trait. If the mother displays the phenotype for the trait then her daughter will as well because she can only give an X chromosome to her daughter. So to answer your question the woman would have an XX genotype (excluding abnormalities such as turner's syndrome and triple X syndrome)
How many alleles does a body cell have for each trait?
Every sex cell has one allele for each trait. after meiosis, pairs of chromosomes separate and alleles for each trait also separate into different sex cells.
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.

How was the mother daughter relationship in the 1500s?
Mother daughter relationships during the 1500s was not very complicated. The mother (if wealthy) would give all responsibilities of parenting to a "nurse", who would be a widow with no kids. The nurse would take care of the daughter or son of the lady of the house until the child was of appropriate age. So there would rarely be any contact with the mother and daughter/son.
