What are the offspring of 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 characteristic than can be passed from an organism to its offspring is a?
Allele
What does an Allele do?
They are traits that are passed from parent to offspring, and therefore develop into phenotype.
Which is expressed a dominant or recessive allele and which is passed on to the offspring?
The dominant allele will always show over the recessive, and both can be passed onto the offspring. To find out exactly which genotypes the children can have you need to make a punnet square!
Is hemophilia a inherited disorder?
Yes hemophilia is a inheerited bleeding dissorder. i read it from my medical book. hemophilia means blood love and can be passed down from mother to daughter. or in some cases mother to son. it is more common for it to passed to daughters. I hope this helped. :)
Is hemophilia communicable?
Hemophilia is not contagious by any means, however it can be passed from parent to offspring in the way of genetics.
Can a AB- mom have a AB- child with a O plus dad?
No to have an AB child the parents must have an A allele in one ine parent and a B in the other so that when they reproduce those two alleles (foumd on the chromosome) can be passed to the offspring and hence the child will be AB blood group. As the father is O (which is a recessive allele) he cannot have either an A or B allele and so the offspring will always have one O allele and either the A or B allele from the mother. The child cannot be AB.
What is hidden in the heterozyotes?
Heterozygotes have two different alleles for a particular gene, where one allele is dominant and the other is recessive. The recessive allele is "hidden" in heterozygotes because it is not expressed phenotypically but can be passed on to offspring.
How is a lethal allele maintained in a population?
A lethal allele is maintained in population for example when you use bug spray on cockroaches there will be at least one cockroach with an allele that protects it from the bug spray, it then breeds and the allele Is passed to it's offspring and they will also be immune to the pesticide. Those babies will most likely breed with each other when they are mature passing on the allele from both of the parents making the offspring 100% immune. It's the same concept for lethal alleles.
Is hemophilia due to heredity?
Yes hemophilia is a inheerited bleeding dissorder. i read it from my medical book. hemophilia means blood love and can be passed down from mother to daughter. or in some cases mother to son. it is more common for it to passed to daughters. I hope this helped. :)
What happens to the fathers mt DNA?
It does not get passed down to the offspring. Only that of the mother does.
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.
