What else can I help you with?
Do you need one or two parents to inherit cystic fibrosis?
you need two parents to get it but one parent to become a carrier. You need two parents with one of the alleles to inherit it but if you have one parent with the allele you might be a carrier. If you have two parents with the allele it does not mean that you will definitely have it. This is because the allele for cystic fibrosis is recessive.
Two parents who were phenotypically normal had to children The oldest was also phenotypically normal but the younger child had cystic fibrosis what is happening in the cross?
Cystic fibrosis is an autosomal recessive genetic disorder, meaning that a child must inherit two copies of the mutated gene (one from each parent) to express the condition. In this scenario, both parents are likely carriers of the cystic fibrosis allele (genotype Cc), where "C" is the normal allele and "c" is the mutated allele. The older child is phenotypically normal, which could mean they are either homozygous dominant (CC) or a carrier (Cc), while the younger child inherited two copies of the mutated allele (cc) from both parents, resulting in cystic fibrosis. This cross illustrates Mendelian inheritance patterns, where two carrier parents can have a child with a recessive condition.
What does it mean that CF is a recessive gene?
The phenotype associated with a recessive gene is only expressed when two copies of the gene are present. For example, if a person has both a recessive allele and a dominant allele for CF, the person does not have CF. The person only has CF if he/she has two copies of the recessive allele.
What vector is used for Cystic fibrosis?
If by vector you mean the organism which causes it, there is none. Cystic fibrosis is a genetic condition.
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.
What is an allie that is covered up or hidden?
If you mean allele, then the answer is a recessive allele. A recessive allele is dominated by a dominant allele, and generally does not show up physically.
Is cystic fibrosis a comunicable or non comunicable disease?
cystic fibrosis is a Genetic disease and in the case of cystic fibrosis, it's not affected others by any external medium like air , water etc that mean it's not a communicable disease.
Can cystic fibrosis kill the person who has it?
Cystic fibrosis is a inherited disease where ususally by the time of 30-35 the person who has it does die.
What does the number os speed for cds mean?

What does recessive allele mean?
Recessive allele disorders are just as they sound - they are disorders that are a result of a prevalent recessive allele in one's genetic makeup. A recessive allele disorder will rarely occur since it is dependent on the crossing of two heterozygous parent cells, but it can lead to interesting consequences. An example of a recessive allele disorder is hemophilia - the body's inability to clot blood - and it has affected much of the European royalty in history, such as Queen Victoria of Great Britain.
How do you write dominant and recessive allels?
normally, the dominant allele is expressed as a capital letter and the recessive allele is expressed as a lowercase letter, if that's what you mean!
