Will the offspring have cystic fibrosis if the mother is FF and father is Ff?

No. Cystic fibrosis is an autosomal recessive disease. Each parent would have to be a carrier of a CF mutation and would be Cc.

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.
Why do only half of a carrier's gametes contain faulty cf gene?
only half of the carrier's gametes contain the cystic fibrosis gene because they only inherit one gene from either the mother or father, not both. For someone to have cystic fibrosis they must have inherited a faulty gene from each parent.
How does a person becomes infected with cystic fibrosis?
The mother and father both have one mutated cystic fibrosis gene. If the child receives genes from the mother and the father that are both mutated, then the child will develop cystic fibrosis. If the child receives only one chromosome containing the CFTR(cystic fibrosis transport regulator: the gene that is mutated in cystic fibrosis), then the child will not develop CF. He will still have the CF gene, but it is a recessive trait, so you need two of these chromosomes that contain the mutated gene to develop the symptoms of CF and be affected by it. Use a punnet square if you still don't understand :)
What term describes the inheritance of cysticfibrosis?
Cystic fibrosis is an autosomal recessive disease. That means that each parent has to carry a mutation and will have a 1 in 4 (25%) chance of having a child with CF. The previous answer is not correct. __________________________________________________________________ You inherit cystic fibrosis from either one parent or both. It is to do with genetic mapping. Cystic fibrosis is a recessive gene and can be carried by our parents even if they do not suffer from it, it's like in a carrier(someone who does not suffer from CF but still has the gene) the cystic fibrosis gene is 'hiding'. When we crete gametes (sperm and eggs) the genes have to split. For example your father could have the gene Ff and they would split and become F f. The capital F is the dominant gene and the small f is the recessive gene, in this case cystic fibrosis. When an egg is fertilised the separate gene from both parents join together. If a man and women have one child, and both parents had the recessive gene of CF then the likelihood of their first child having cystic fibrosis is high, 50% in fact. Here is a diagram which might help explain Parents Mother + Father Genotype (genes) Ff Ff Gametes(sperm+egg) F f F f Offspring FF ff 50% 50% I hope this helped a little. I didn't go into full detail becasue there is a lot more to it then what i have said and it is a lot more comlicated. If you can, try to go on a revision site which may help.
If the father is a buck then what is the offspring and mother?
If the father and mother are deer, the mother would be called a doe and the offspring would be called fawns, but the answer might be different for species other than deer.
Where do the offspring of sexual reproduction get its genes from?
The mother and father
What are recessive disorders?
When a genetic disorder is recessive, that means that two copies of the gene are necessary to have the trait or disorder. One is inherited from the mother, and one from the father. Disorders of this type include: cystic fibrosis, sickle cell anemia, and Tay-Sachs disease.
Why does an offspring share a lot of traits with its mother?
because the baby is in the mother not the father
What are recessive genetic disorder?
When a genetic disorder is recessive, that means that two copies of the gene are necessary to have the trait or disorder. One is inherited from the mother, and one from the father. Disorders of this type include: cystic fibrosis, sickle cell anemia, and Tay-Sachs disease.
What is the different between parent and mother?
A parent can be a father or a mother. A mother is a female who has given birth to offspring
How do you use the word offspring in a sentence?
John was the offspring of his mother and father. The offspring of the white cat and the black cat is a grey cat.
What's Cystic fibrosis?
Cystic fibrosis is a genetic disorder which affects the lungs and pancreas. It causes the lungs to get clogged with mucus, which in turn makes the lungs a breeding ground for bacteria. In the pancreas, it blocks the pancreas from absorbing enzymes, which makes its victims prone to malnutrition. Often times, they have to take treatments such as lung therapy every day, as well as enzyme supplements on a daily basis. The average life expectancy is 37.Cystic Fibrosis is caused by a defective gene which causes a thick, sticky mucus. It builds up in the lungs and pancreas (the organ that helps to break-down food.) Cystic Fibrosis results in life-threatening lung infections and digestive problems. Symptoms are varied, but the most common are: No bowel movements in first 24 - 48 hours of life (baby!) Stools that are pale or clay colored, foul smelling or float. Infants can have salty tasting skin. Recurrent respiratory infections, such as pneumonia or sinusitis. Coughing/wheezing. Weight loss or can't gain weight normally in childhood. Diarrhea, delayed growth and fatigue.Cystic Fibrosis is the most common fatal genetic disease occurring in about 1 in 30,000 births. The gene must be inherited from both the mother and the father. Children inheriting only one copy of the gene are carriers but do not display symptoms. Average life expectancy for Cystic Fibrosis is approximately 32 years of age. There are many treatments but no cure. People with Cystic Fibrosis are at high risk of developing other conditions such as Cystic Fibrosis related Arthritis and Cystic Fibrosis related Diabetes, Liver failure and ultimately respiratory failure leading to death. Once a person with Cystic Fibrosis loses enough lung function the only other treatment is a lung transplant
