What are two genetic diseases besides Down syndrome?
Hemophilia Sickle-Cell Anemia Cystic Fibrosis for a fuller list look in the related link below.
Is it possible for a mother to have two kids with different father be born with cystic fibrosis?
Depends. If your mother has cystic fibrosis and your father is a carrier, there is a 50% chance that any of their children will have cystic fibrosis. If the father is not a carrier, no children will have cystic fibrosis, but they will all be carriers.
Identify two examples of inherited conditions and disease?

What would be the genotype of a person with cystic fibrosis?
The genotype of a person with CF is cc. The genotype of a carrier of a CF mutation is Cc.
What is the ratio of people with Cystic Fibrosis?
According to the Cystic Fibrosis Trust's website:Cystic Fibrosis (CF) is one of the UK's most common life-threatening inherited diseases.Cystic Fibrosis affects over 9,000 people in the UK.Over two million people in the UK carry the faulty gene that causes Cystic Fibrosis - around 1 in 25 of the population.If two carriers have a child, the baby has a 1 in 4 chance of having Cystic Fibrosis.Cystic Fibrosis affects the internal organs, especially the lungs and digestive system, by clogging them with thick sticky mucus. This makes it hard to breathe and digest food.Each week, five babies are born with Cystic Fibrosis.
Name two genetic disorders?
Two genetic disorders are Turner's syndrome and cystic fibrosis.
Why do only white people get cystic fibrosis?
Most white Europeans do not get cystic fibrosis. There is, however, a greater occurence of the recessive gene responsible for cystic fibrosis in Caucasians and Ashkanezi Jews than other races.
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?
If both parents are carriers on cystic fibrosis, just because two children may have the disease it doesn't mean that say,a further 3 children in future will be "normal". Inheriting genes is like a lottery. I can say though that because cystic fibrosis is recessive, every offspring born under carriers will always have a 75% chance of being phenotypically normal.
How do you deterime phenotypes?
phenotypes are decided by the alleles for that particular characteristic, by a dominant or two recessive alleles. For example, cystic fibrosis has a recessive allele so the phenotype of cystic fibrosis would only appear if there were two of the recessive allele, one from each parent, were present. A heterozygous carrier of the cystic fibrosis allele would show the phenotype of not having cystic fibrosis. So to determine the phenotype simply find out which allele is dominant and find what alleles each parent has the the probability of each phenotype can be calculated
Is cystic fibrosis common?
Cystic fibrosis is the most common life threatening disease in the UKOne in 25 people have the cystic fibrosis gene in them (but may not have the disease). Most people aren't even aware that they carry the gene. If two people who have the gene reproduce, the odds that they have a child with cystic fibrosis is 1 in 4. The chance that they will have a child who carries the gene but doesn't have the disease is 2 in 4 (half). The chance that they have a child who does not have the disease or carry the gene is 1 in 4.
Is cystic fibrosis an infectious disease?
Good Question. The answer is cystic fibrosis is not contagious, however, people with cystic fibrosis tend to carry bacterial infections that can cause serious issues to other people with CF, so infection control procedures should be used when two or more cystics are around each other. General population folks need not fear of getting cystic fibrosis from others - it's a hereditary disease.
What is the probability of two healthy people where one is a carrier being parents to a child born with cystic fibrosis?
If only one person is a carrier of cystic fibrosis than there is no chance of having a child with it. Both parents have to be carriers and even then there is only a 25% chance. If only one carries than there is a 50% chance that their children will carry but will not have cystic fibrosis.
