Does Fibrodysplasia Ossificans Progressiva have a bad chromosome?
Wiki User
∙ 14y ago
The gene that is mutated in a person who has Fibrodysplasia Ossificans Progressiva is called the ACVR1 gene. A small mutation in one of the two copies of the ACVR1 gene modifies the meaning of its genetic message, so a defective protein is made.

Can a male be a carrier for hemophilia?
The gene for hemophilia is found on the 'X' human chromosome. However it is a recessive gene so if a woman (who has two 'XX' chromosomes) has one bad 'X' and one good 'X' she will not have hemophilia but will be a carrier .If she has female children and their father is not a hemophiliac, then half of her daughters may carry the bad 'X' chromosome but non will manifest the disease.However, if her children are male then her sons will have an 'X' chromosome inherited from her and a 'Y' chromosome inherited form the father and there is a 50% chance that the 'X' chromosome inherited will be the bad one. If the son inherits the bad 'X' he will be a hemophiliac and if he lives to father any daughters then all these daughters will be hemophilia carriers (because they must inherit his (bad) 'X' chromosome).It is possible for a woman to manifest hemophilia if the mother is a carrier and the father is a hemophiliac. In this case it is possible for a daughter to inherit the bad 'X' from the father and the mother's bad 'X' giving the daughter two bad 'X' chromosomes.
Nondisjunction can alter the number of chromosome as well as autosomes?
Nondisjunction is a very bad thing and cells and can lead to lying of the cell.
The faillure of chromosomes to separate during meiosis is called?
Its called disconjunction. Sometimes it is so bad that they have a miscarriage or the following happens:Trisomy (extra chromosomeso have 47 chromosomes instead of 46)Down's syndrome (andextra number 21 chromosome)Klinefelter's syndrome (males with an extra X chromosome...XXY)
Is bipolar disorder found on the x-linked chromosome or y-linked?
bipolar disorder is found on the x-linked chromosome. Since female has 2 pairs of X chromosome. The effect of bad gene is compensated by other pair. Hence it carries to generations without being noticed. Also it is being liked to reproductive cycle of females. Where as male has one X and One Y chromosome. Hence a faulty X has no way to compensate. So if a male has bipolar disorder it is most likely to be of bipolar disorder of type 1 (most severe). Thought data shows males have less tendency of having bipolar disorder in percentage terms.

Why is colorblindness found to be inherited into males more than females?
Most color deficiencies are sex linked, meaning the defective genes are on the sex chromosome. In this case, the X chromosome is affected. Since males only have one X chromosome, all males with this particular defective genes will have this condition. Females have 2 X's, it's unlikely that both X's have bad genes at the same time.

Why Are males more often hemophiliac?
Hemophilia is a recessive, sex-linked, X chromosome disorder. It would have to be present on both X chromosomes to present in females. It only has to be present on the single X chromosome to present in males.
Why are males prone to colorblindness?
The classic red-green color blindness is carried on the X chromosome. Men get the x from their mother and the y from their father. If the x has the bad gene then they will be color blind. If a woman gets the gene from her mother she will be a carrier and able to pass it to her sons (or the carrier state to her daughters) but will be able to see because she has a good gene on the other x chromosome. There are other forms of color blindness that are inherited in other ways so women can be color blind.
Which of the parents can pass the allele for hemophilia to a son. Explain?
The allele is on the X-chromosome, of which females have two, but males only one (the other being a Y-). If a woman has one faulty and one good X, she shows no symptoms, but stands a 50% chance of passing the bad one on to her son or daughter.
What are the unique facts about color blindness?
Not being able to see color in some cases. Mild color blindness might just be an inability to distinguish between colors like green and red. That is sometimes the case, not always. Did you know that 99% of all color blind people are not actually color blind, but color deficient? Does that help?
What genetics are inherited by the father?
~uh... the father cannot inherit any genes, unless it's from his parents...but if you want to know what a father passes down to an offspring, I have that answer = Females are rarely affected by sex-linked traits because ______.? = a. female have one X chromosomeb. X-inactivation in malesc. X-inactivation in femalesd. X chromosomes in males generally have more mutations than X chromosomes in femalese. mutations on the X chromosome are not passed down to females, but are always passed down to malesMales are an "X" & a "Y" so I have no idea. I do know that Parkinson's Disease is passed from mother to son. My husband is concerned about that.*Female is XX and Male is XYIf the female is to suffer from a sex linked disease, she has to pick it up from the father's X chromosome. If the disease is "recessive", then it is masked over by the Mother's X chromosome that she passed down to the daughter. If the disease is on the father's X chromosome and is dominate in nature, that's a little different situation. The mother's X chromosome may carry a dominate allele for that same chromosomal location which may or may not mask over the diseased gene. In any case, it is the mother's X chromosome handed down to the daughter that reduces the likelihood of her experiencing a sex linked disease.The answer would d.)a.) almost seems right but females are XX not X0, generally. Though, after X chromosome inactivation, the female does have only one X chromosome, but ... she also has the X chromosome from the father. So, she does have XX chromosomes. d.) is your answer.See: Sex Linkagehttp:/en.wikipedia.org/wiki/Sex_linkage*Answer is probably C.A female is XX, but during development of the zygote, one of the X chromosomes is randomly turned off. This process is referred to as X-inactivation. If the sex linked trait is on the off X chromosome, then the female will not be affected.The answer is not D because the X chromosome carried by females that is "off" accumulates more mutations than the one in males since there is still one good copy of the chromosome left. The answer is definitely not A or B. Males need their one X chromosome to develop properly. E is partially right; mutations are not ALWAYS passed down to females, but a female can be a carrier for a genetic disease.Males have XY sex chromosomes while females have XX chromosomes & the fact is; These two chromosomes ( X & Y ) differ in shape. The X chromosome is larger than the Y chromosome & thus has a greater capacity of carrying genes. That is to say most genes are carried by the X chromosome whereas only a few genes are carried in the Y chromosomes.Therefore it takes only one defective gene eg. that causing Colour blindness in males for it to have phenotypical impact on the individual whereas it would take two defective genes on both X chromosomes in females for it to have phenotypical impact on the individual. Only one defective gene on either of the two X chromosomes in females results to a carrier individual, a condition whereby the individual carrying the defective gene( usually recessive) is only affected genotypically but looks normal phenotypically, she only carries the gene in her chromosomes but due to its recessiveness, it does not show its effect phenotypically.Due to this simple reason more males are affected by sex linked defects than females since females, due to the nature of their sex chromosomes can either be normal, carriers or affected( they have 3 alternatives) while we male only have 2(normal or affected)PS. You should know that most sex linked defects are carried on recessive genes( this is a fact)With this little lecture I'm sure you can pick the right answer from your multiple choice.Good luck.*c.the gene is carried on the X chromosome, and a girl has the trait on ONE of her X chromosomes, then she will need it on the other for it to be expressed MOST OF THE TIME. for guys, if they get the mutation on their ONLY X chromosome, they're stuck with it because only the X can carry such mutations** *:there are 2 X chromosomes in male and only 1 X chromosome in female, and X is where all the stuff happens, so male are twice likely to have a mutation in their sex chromosomes than females.* I believe the answer is C. The X chromosome does not affect females. Males are affected by the XY, and females by YY. ** 3 weeks ago 0% 0 Votes** 0 Rating: Good Answer ** 4 Rating: Bad Answer ** Report Abuse~scrunnchy
