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 many alleles does a normal gamete have?
Normal gametes should contain one allele from each gene.
Gametes contain one half one quarter or is equal to the number of alles found in other cells in the body of an organism?
Gametes contain half of the number of chromosomes as somatic cells (the other cells of your body). These chromosomes have the same number of alleles on them as somatic cells, but gametes contain one allele of each gene while somatic cells contain two alleles of each gene. So, they contain half the amount of alleles that the rest of your cells do.
Which of the following is the first step in gene therapy?
Identifying the faulty Gene. Identifying the faulty Gene that causes the disease.
Why do you need gene therapy?
gene therapy is when a faulty gene is repaired or replaced
Epidermolysis bullosa simplex?
Hello, I see you are asking "What are the causes for epidermolysis bullosa?" EB is caused by a faulty gene (gene mutation) that makes skin more fragile. A child with EB might have inherited the faulty gene from a parent who also has EB. Or they might have inherited the faulty gene from both parents who are just "carriers" but don't have EB themselves.

Can cystic fibrosis gene be inherited from one parent?
For a baby to be born with Cystic Fibrosis, both parents must be carriers of the faulty CF gene. Where both parents carry the faulty gene, each child has a one in four chance of having CF, a two in four chance of being a carrier and a one in four chance of not having any CF genes.
Is cystic fibrosis a genetic dosorder?
Yes it is. For a baby to be born with Cystic Fibrosis, both parents must be carriers of the faulty CF gene. Where both parents carry the faulty gene, each child has a one in four chance of having CF, a two in four chance of being a carrier and a one in four chance of not having any CF genes.
Is cystic fibrosis geneitc?
Yes it is a genetic disorder. For a baby to be born with Cystic Fibrosis, both parents must be carriers of the faulty CF gene. Where both parents carry the faulty gene, each child has a one in four chance of having CF, a two in four chance of being a carrier and a one in four chance of not having any CF genes.
Do gametes have two alleles per trait and organisms have one?
Gametes contain only one set of chromosomes. They only have one allele for each gene because they are designed to combine with another cell in order to form an organism.
Why is gene therapy using gametes controversial?
Because its not natrual.
What is it called When the two gametes that fuse to form a zygote contain different alleles of a given gen?
The zygote is heterozygous for that gene. Which ever one of the genes of the parents is dominant, then the zygote has that gene, but also carries the recessive trait from the other parent.
Do most heritable differences are due to gene shuffling that occurs during the production of gametes?
gene shuffling
