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 else can I help you with?
Is hemophilia communicable?
Hemophilia is not contagious by any means, however it can be passed from parent to offspring in the way of genetics.
Is hemophilia inherited or environmentally transmitted?
It is inherited.
What condition is a hereditary bleeding disorder that is transmitted from mother to her sons?
Hemophilia
What is the Mode of inheritance hemophilia?
Transmitted by a dominant gene. If that gene is inherited from either parent, the offspring will develop HD. If the gene is NOT inherited, then the offspring will not have HD- AND cannot pass the gene to their offspring.
Hemophilia results from an allele then is?
Recessive?? (i.e., you would need to inherit one from each parent to have hemophilia)
Does a human offspring inherit hemophilia from the mother or father?
Hemophilia is sex linked. Males inherit from their mother, daughters are carriers if the defective gene is inherited from one of either parent. A female must inherit two copies of the defective allele to have hemophilia .
Hemophilia is a sex-linked recessive disorder. Mary does not have the disease, but both of her brothers do. Neither of her parents have the disease. What are Mary's parent's genotypes (* indicates presence of the hemophilia allele)?
X*X and XY
