A question from tin of roses: If someone wanted to find out if they are a cystic fibrosis carrier…?
how would they do this? Is it gene therapy?

Best answer:

Answer by morgan
There is a genetic test that can be performed. A blood sample is taken, and lab technicians run procedures to determine whether a defective CF gene is present.

The test is generally offered to prospective parents, especially if they have a family history. If you or your partner are trying to get pregnant, you can ask your OB/GYN for the test.

Question posed by misty: Can someone help me with genotype frequency?
A rare recessive allele inherited in a mendelian manner causes cystic fibrosis. A phenotypically normal man whose father had CF marries an unrelated woman and they consider having a child. If the frequency of heterozygotes for CF in the population is 1 in 50, what is the chance that the couples first child will have CF? Give reasons for your decision.

Thanks for your help, i’ve been trying to figure out this question for ages

Most detailed answer:

Answer by kidachan
alerighty so a 1 in 50 chance in apopulation of a hild being born with CF = a 2% abundance in a population (2 out of 100) right? well then their is a 2% chance that the wife has the dangerous allele

the clid would definatly recive for sure one recive allele from the father and then would have about a 2 percent chance of gettiing the allel from the mother which would give the child a 2% chance of coming down with cf

if this were a real situatio i would recomend that the mother looks into her family back ground to see if any of her family members have had the dangerous dease at all for as far back as she can trace it

A question asked by fffan215: If someone is a dormant carrier of cystic fibrosis, what are there symptoms (if any) and how is it passed on?
My sister found out she has cystic fibrosis today. She said that she found out she has a portion of it and if her boyfriend has it too then there soon to be baby may have it. She wont stop crying and I want to know if this is that serious… and since she only has a dormant portion of the disease and its genetic.. if her or I could be affected by it’s symptoms. Thanks for your help I truely appreciate it.

Chosen answer:

Answer by KB
You and she won’t have symptoms. She just has the recessive gene for it and so does her boyfriend. The only way their child will get it is is they both end up giving her the recessive gene for it.

The child gets a gene from each parent for everything. In order to have this disease, you must have two recessive genes (the CF gene from each parent). If you only get one recessive gene from one parent and one normal gene from the other parent, you still won’t have it. You will just be a carrier of the gene like your sister. Or the child could get a dominant normal gene from each parent and then not be a carrier and not have the disease (best case scenario).

Basically, in perfect genetics, their baby has a 25% chance of getting CF, a 50% chance of being a carrier, and 25% chance of being completely free of the gene. The odds are the baby will not have CF itself but there is still that chance.

I wish her luck.

Question posed by angeleyez2936: Can someone explain this genetics question to me?
A couple who are both carriers of the gene for cystic fibrosis have two children who have cystic fibrosis. What is the probability that their next child will be phenotypically normal?

The correct answer is 75% but I don’t see how?

Selected answer:

Answer by beanthedoctor
The point is that the probability doesn’t depend on previous children. So, if both parents are normal and carry a copy of cystic fibrosis gene, then every time they have a kid they have 50% x 50% (25%) chance of it getting both copies of the cystic fibrosis gene. Therefore, 100-25 = 75% chance they will have a normal child every time..
