What is the chance that a hemophiliac father and a non hemophiliac but a carrier for the hemophiliac gene mother will give rise to an offspring with hemophilia?
What is the chance that a hemophiliac father and a non hemophiliac but a carrier for the hemophiliac gene mother will give rise to an offspring with hemophilia?
MOTHER IS A CARRIER AND FATHER HAS HEMOPHILIA 50% chance that each son will have hemophilia. 50% chance that each daughter will be a carrier of the hemophilia gene. 50% chance that each daughter will have hemophilia.
What is the genotype of a male without hemophilia?
Males having one abnormal gene are affected with hemophilia and will transmit that abnormal gene to all their daughters, but to none of their sons….Expression and Transmission.
| Phenotype | Genotype |
|---|---|
| Normal male | XHY |
| Normal female | XHXH |
| Affected male | XhY |
| Carrier female | XhXH |
What is the probability that a male offspring will have hemophilia?
a 25% (one in four) chance of having a son with hemophilia. a 25% chance of having a son with normal blood clotting. a 25% chance of having a daughter who is a carrier. a 25% chance of having a daughter who has hemophilia.
Why is it that the father never passes on the gene for haemophilia to his son?
Haemophilia is a sex-linked recessive disease. The defective genes present on the X chromosome only and not on the Y chromosome. As the father always contributes a Y chromosome and never passes an X chromosome to his son, the gene for haemophilia can never be passed from a father to his son.
What famous person has hemophilia?
The love of Elizabeth Taylor’s life and a Shakespearean actor for the ages, Richard Burton starred in 61 films and 30 plays — and was the first Hollywood star to reveal he had hemophilia. In fact, Burton and Taylor set up the Richard Burton Hemophilia Fund in 1964 to help find a cure for hemophilia.
Can animals have hemophilia?
Hemophilia B is caused by a deficiency of coagulation Factor IX (9) and has been found in over 25 breeds of dog. Like dogs with Hemophilia A, dogs with Hemophilia B may spontaneously bleed into the skin, chest, abdomen, muscles, or joints. Also, there may be excessive bleeding from a surgery site.
Can cats have hemophilia?
Hemophilia A (Factor VIII deficiency) is the most common inherited bleeding disorder in cats. Affected cats may show prolonged bleeding after surgery or injury but rarely bleed spontaneously, probably because of their agility and light weight.
Can a woman with hemophilia have a baby?
If the mother is a hemophilia carrier, there is a chance that the baby will be born with hemophilia. In families with a known history of hemophilia, or in those with a prenatal genetic diagnosis of hemophilia, one can plan special testing for hemophilia before the baby’s delivery.
Can males pass on hemophilia?
A father passes down his Y chromosome to his sons; thus, he cannot pass down a hemophilia allele to them. Without the hemophilia allele, the sons will not have hemophilia and can’t pass it down to their children.
Why do men only get hemophilia?
This means that males only have one copy of most of the genes on the X chromosome, whereas females have 2 copies. Thus, males can have a disease like hemophilia if they inherit an affected X chromosome that has a mutation in either the factor VIII or factor IX gene.
Is it possible for a female to have hemophilia explain?
Hemophilia can affect women, too Females can also have hemophilia, but it is much rarer. When a female has hemophilia, both X chromosomes are affected or one is affected and the other is missing or non-functioning. In these females, bleeding symptoms can be similar to males with hemophilia.
