You can be a carrier of a recessive gene as part of your genotype.
As long as a persons genotype consists of at least one recessive gene, they can pass it on to offspring to give them the disease, which makes them a carrier. Since this persons genes are both recessive, it is definite that they will pass on the 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.
Most genes have two copies of each gene with dominant gene "trumping" the recessive one. The gene is recessive because it is said not to do much of anything unless paired with another recessive gene, but if paired with a dominant gene, the dominant gene wins.
A male can inherit an autosomal recessive disorder from both of his carrier parents, who each pass down a copy of the mutated gene. This results in the male having two copies of the mutated gene, leading to the manifestation of the disorder.
A person considered a carrier typically has one normal (dominant) allele and one mutated (recessive) allele for a specific gene. This means they do not exhibit symptoms of the genetic condition associated with the recessive allele but can pass the mutated allele to their offspring. For example, in autosomal recessive disorders, carriers are asymptomatic but can potentially have affected children if their partner is also a carrier.

Cystic Fibrosis is recessive. If you have one CF gene and one non-CF gene, you will be a carrier but not have CF.
No, because he or she cannot pass the gene on to his or her offspring (because he or she does not have a copy of the gene).
No, because he or she cannot pass the gene on to his or her offspring (because he or she does not have a copy of the gene).
You don't have it but have the gene and are a carrier and could pass it on.
A carrier means that you have the gene for the disorder, but because the gene is recessive (meaning that it only shows when you have two recessive genes) and you obviously have a dominant gene as well, you won't show the disorder. Someone who actually has the disorder has two recessive genes. D = dominant gene r = recessive gene Dr = carrier, no signs rD = carrier, no signs DD = not a carrier, no signs rr = has the disorder
When a parent for example has one dominant and onee recessive e.g Fe and another parent is a carrier for it e.g ee this will make the gene produce a trait of the offspring having a 50% chance of being a carrier

The mother has a 50% chance of passing the defective recessive gene to her daughters who will be carries of the disorder (like their mother).
A recessive gene is a gene that does not express itself in the presence of a dominant gene of the same trait. When an individual inherits two recessive genes for a trait, the recessive gene will be expressed.
Most genes have two copies of each gene with dominant gene "trumping" the recessive one. The gene is recessive because it is said not to do much of anything unless paired with another recessive gene, but if paired with a dominant gene, the dominant gene wins.
