Probability??
Question: A man with hemophilia is having a child with a woman that is a recessive carrier for hemophilia. What is the probability that any of their children with suffer from hemophilia?
Answers: 25% chance of having a girl with it, 25% chance of having a boy with it ...50% total chance of having a child with it.
25% chance of having a girl that is a carrier.
25% chance of having a normal boy.
The hemophilia gene is found in the sex chromosomes. The missing arm on the Y chromosome (the chromosome responsible for making a boy) is what corresponds to the affected part of the gene on the X chromosome. A boy child only needs to have one affected X gene to become a hemophyliac, where as a girl needs to have both genes affected.
For a boy child, the dad will give his Y chromosome (which does not carry the gene). The mom has one affected and one not affected gene, so the boy will have a 50% chance of accquiring it.
For a girl child, the dad will give his affected X chromosome, so a girl child will always have atleast one affected gene, meaning at best she would be a carrier. Whether she would be just a carrier or have the disease would depend on whether she got the affected gene or the unaffected gene from her mother.
Man is Hh, same as the Woman (hemophilia only affects woman who are HH, it affects Men even when its Hh i believe).
Therefore the possible combos are (out of 4 children):
HH
Hh (Twice the chance)
hh
In conclusion, if their child was Male it would have a 3 in 4 chance, if the child was female, itd have a 1 in 4 chance.
Be aware the haemophiliacs make it a point not to breed, its an exremely heavy burden to give to a child.

none of the above. Down syndrome occurs when the creation of sperm or egg cells (meiosis) does not occur properly. an extra chromosome (#21) is inadvertently left inside the cell. you and I have two o
I agree. Do your own homework.
Spina Bifida is caused by not having enough folic acid in the mother's diet during pregnancy. Chances can be decreased greatly by taking a folic acid supplement prior to conception and during pregnanc
What are the genetic changes related to Down syndrome?
Down syndrome is related to chromosome 21.
Most cases of Down syndrome result from trisomy 21, which means each cell in the bod

Please do not quote my answers... it has been a while since AP Bio!! Recesive genetic disorders just mean that both parents have to be carriers of a disease for a child to have it!! If i am not mistak
It's believed to be porphyria - the malady that affected poor King George III - but nowadays they can test for it at birth and administer an appropriate medication to stop it developing.

Still studying the genetic link to angelman's syndrome. From the research I have done, and who knows how much information on the internet is correct but I believe it is a sex-linked gene.
dominate traits can be expressed in the heterozygous gene state. This means if you have one dominant and one recessive gene the dominant will prevail. ie one blue and one brown, brown will prevail.
the genes of your parents.
Let
R= Dominant trait
r= Recessive trait
Homozygous dominant= RR
Homozygous recessive= rr
Heterozygous= Rr
Heterozygous individuals will have both traits, but its ph

Polio is not genetic.
