What is someone’s genotype if they are a carrier?

An organism’s genotype represents the two alleles inherited for a given trait. For an organism to be a carrier, the genotype must include one copy of a recessive allele. Carriers do not exhibit the physical trait, but have a 50 percent chance of passing the gene on to an offspring.

What genotype is a female if they are a carrier?

Two female offspring are produced for every two male offspring. One male and one female offspring inherit normal genes. One female is heterozygous for the hemophilia trait and is considered a carrier.

What is the FF genotype?

Genotype is the genetic makeup of an individual eg Ff or FF. Phenotype is the physical appearance eg carrier of cystic fibrosis. … That means that it shows up in the phenotype whether you have one copy of it, or two copies. A Recessive allele only has an effect if you inherit two copies eg ff (cystic fibrosis).

Is it possible to be a carrier of a dominant gene?

The dominant gene outweighs the recessive gene, so while a carrier does not develop the disease, a carrier can pass on the gene with a mutation to his or her child.

What does genotype BB mean?

An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB. An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype.

Can someone be a carrier for a dominant disorder?

Dominant genetic disorders are those in which a mutation in just one copy of the gene pair is required for the disorder to develop. An individual who carries a mutation for a dominant disorder usually manifests the disorder and therefore tends to be known as being affected by, rather than a carrier of, that disorder.

What does it mean to be a carrier of an allele?

A carrier is an individual who carries and is capable of passing on a genetic mutation associated with a disease and may or may not display disease symptoms. Carriers are associated with diseases inherited as recessive traits. … An individual having one normal allele and one mutated allele does not have the disease.

What are carriers give examples?

An example of a carrier is a postal worker who delivers mail. An example of a carrier is a cat carrier that you would use to take your cat to the vet. An example of a carrier is the company such as AT&T that provides your telephone service.
