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.

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.
Are gametes heterozygous?
Gametes are typically haploid cells, meaning they contain only one set of chromosomes. Therefore, gametes are not heterozygous, as they have only one allele for each gene.
Which of the following is the first step in gene therapy?
Identifying the faulty Gene. Identifying the faulty Gene that causes the disease.
How many gametes in AaBB?
Two gametes, each carrying one copy of the A gene and one copy of the B gene.
How many alleles does a pea plant gamete have for the height gene?
TT or Tt
How many alleles does a normal gamete have?
A normal gamete has one copy of each allele for a particular gene, so it carries a total of two alleles.
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 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.
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.
Who is the carrier in Congenital Adrenal Hyperplasia?
Congenital Adrenal Hyperplasia is an autosomal recessive disorder, which means that it typically requires both parents to pass on a copy of the faulty gene for a child to be affected. Carriers of the condition usually do not show symptoms themselves but can pass on the gene to their offspring.
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.
