What is the probability that their son has hemophilia?
Hemophilia is passed down from mother to son. It is extremely rare for a woman to have hemophilia. It is necessary, though, for a woman to be a carrier of the disorder for her son to acquire this disorder. Females have two X chromosomes whereas males only have one. When a boy is born, he takes one X chromosome from his mother and one Y chromosome from his father. Therefore, he can only get hemophilia through his mother. Example One: Mother(Carrier)+Father(Non-Affected)=50% chance of their son acquiring the disorder and 50% chance of their daughter being a carrier. Example Two: Mother(Non-Affected)+Father(Hemophiliac)=All sons will be non-affected and all daughters will be carriers.
A girl is a hemophiliac whose mother is normal what are the genotypes of her parents?
The girl must have inherited an X chromosome with the hemophilia gene from her mother, who is a carrier (heterozygous X^HX^h). The father must have contributed a Y chromosome, as males determine the offspring's sex. The father's genotype is not directly related to the daughter's hemophilia status.
If you know a woman has hemophilia what can you infer about her parents genetype?
Her father has to have hemophilia as well, and the mother is a carrier or also has hemophilia. So if we pretend that the hemophilia gene is "x", you need to have "xx" to have hemophilia. The father must have the genotype "Yx" and the mother has the have "Xx" or "xx".
Could two phenotypically normal parents have a child with Hemophilia A?
XhXh - with hemophilia XhXH- carrier of hemophilia
An individual with a recessive allele for an undesirable trait is called?
A carrier. This individual may not show the undesirable trait, but can pass on the recessive allele to their offspring.
Who was willis carrier father and mother?
Elizebeth R. Haviland&Duane Williams Carrier
A female who is a carrier of Fabry's disease has what chance of having a daughter who is a carrier?
The mother has a 50% chance of passing the defective recessive gene to her daughters who will be carries of the disorder (like their mother).
Why is a son who receives the allele for combinations from his mother always colorblind?
Since the mother would be considered a carrier, the gene will be produced in the offspring. the son will receive that gene and will be colorblind.

Can HIV be self given?

Is there a way to detect a carrier of autism?
Yes, testing the mother for skewed x-inactivation.
How do you know if a characteristic or disorder is sex linked?
If it occurs most commonly in males, or if the mother is a carrier.
Sam has hemophilia. Sam's brother mother and father do not have hemophilia. Draw a pedigree showing who has the disorder and who is a carrier?
In a pedigree chart, Sam would be represented by a filled square (male) or circle (female) to indicate that he has hemophilia. Since Sam's brother, mother, and father do not have hemophilia, they would be represented by unfilled squares (male) or circles (female). However, Sam's mother would be a carrier of the hemophilia gene, so she would be represented by a half-filled circle. The pedigree would show Sam with hemophilia, his mother as a carrier, and his brother, father, and other family members without the disorder.
If a color blind man has a color blind daughter then the mother has to be color blind as well?
The father has to be colorblind for the daughter to be colorblind because both X chromosomes must have the colorblindness gene in females because the colorblind gene is recessive. If only the mother is color deficient, then she merely passes on the gene to one of the X chromosomes in a female. If both the mother and father are both colorblind, then both X chromosomes in the female are effected and the female is colorblind. There are two scenarios in which a daughter may be born colorblind. 1. The father is colorblind and the mother is a carrier of the colorblind gene. The daughter will be either colorblind or a carrier of the colorblind gene. 2. The father and mother are both colorblind. If this is the case, then all of the children will be born colorblind.
