Because a recessive condition requires two copies of the gene (one from each parent) to be present in order to manifest. If only one parent is a carrier, the individual would inherit one copy of the gene, but would not develop the condition because they would need a second copy from the other parent in order for the condition to be expressed.
A carrier. This individual may not show the undesirable trait, but can pass on the recessive allele to their offspring.
They are a carrier of the disease but do not show any symptoms because they have one normal allele that can compensate for the recessive disease-causing allele. If they have children with a partner who is also a carrier, there is a chance their offspring may inherit two copies of the disease-causing allele and develop the disease.
You can be a carrier of a recessive gene as part of your genotype.
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.
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.

A genetic carrier has a dominant and a recessive version of an allele. Normally, the term genetic carrier is used in relation to genetic illnesses where two copies of the recessive allele cause that illness. Therefore, a carrier does not have the illness themself (as the dominant, non-disease allele is expressed over the recessive allele). However, they have the ability to create an offspring who has the double recessive genotype and therefore has the condition if they mate with another carrier or someone who is double recessive (who has the disease).

Yes because most diseases or disorders are recessive and therefore there can be carriers that are normal.
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.

Let's see what combinations can be formed.HH, HH, Hh, Hh.So, yes their offspring can contain the recessive allele.(THe offspring can be a carrier of the recessive allele.)However, since it is impossible for the offspring to be homozygous recessive,the recessive trait/gene will not show in the offspring's phenotype.Hope that helps!

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
If one parent is a carrier then the baby has a 50% chance of being born a carrier as well, but the baby will be healthy as the gene is recessive.
Phenylketonuria is an autosomal recessive genetic disorder. The enzyme phenylalanine hydroxylase is necessary to metabolize phenylalanie, but when this enzyme doesnt work, phenylaline accumulates and is detected in the urine. The disease is detected during pregnancy, and if treated right away the newborn can develop normally. However, if left untreated, the brain will not develop properly.
