Whose chromosomes determine the sex of offspring in humans?
The father's chromosomes determine the sex of offspring in humans. Specifically, the father's contribution of either an X or Y chromosome determines whether the offspring will be male (XY) or female (XX).
Who do males inherit sex-linked recessive traits from?
Males inherit sex-linked recessive traits from their mothers. This is because males have an X chromosome from their mother and a Y chromosome from their father, so any recessive traits on the X chromosome will be expressed in males.
A woman is a carrier for hemophilia what is the chances for sons with hemophilia if the father does not have hemophilia?
If the mother is a carrier for hemophilia, there is a 50% chance that her sons will inherit the hemophilia gene, but only if the father does not have hemophilia. This is because sons inherit the X chromosome that carries the hemophilia gene from their mother. If the father does not have hemophilia, the son will not inherit a healthy X chromosome from him to compensate for the defective X chromosome from the mother.
What is the probability that their son has hemophilia?
The probability that their son has hemophilia is 50% if the mother is a carrier and the father is unaffected. Hemophilia is an X-linked recessive disorder, so there is a 50% chance that a son will inherit the affected X chromosome from his mother.
How is haemophilia genetically passed on?
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.
What can the mother do to the father if the test shows it is his child?
Well the mother has to allow the father to see the child a little bit and the judge will decide how though!
Why could a girl with Turner's syndrome have red-green color blindness even though both of her parents have normal vision?
Turner's syndrome is caused by a missing or incomplete X chromosome. Since the gene for red-green color blindness is located on the X chromosome, if the girl inherited the X chromosome carrying the red-green color blindness gene from her father, she could have the condition even though her father has normal vision. Her mother would be a carrier of the gene, but with two X chromosomes, she likely does not exhibit red-green color blindness herself.
Why is it hemophilia occur mostly in male?
"X-linked" disorders are more commonly observed in males do to the chromosomal make up of boys and girls. As you are probably already aware, females have two X chromosomes and no Y chromosomes. Males on the other hand have one Y chromosome and only one X chromosome. Since this is the case, when a male receives an X chromosome with a mutation on it, they have to use that X chromosome as a "blueprint" even if the information on it is wrong. When a female has a mutation on one of her X chromosomes, she typically has another non-mutated X chromosome from which she can get the correct information.
How does a person get hemophilia?
Hemophilia is passed down from mother to son through your genes. 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.
