It is called "carrier".


What is being carried by a genetic carrier?

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).

You can be a carrier of a recessive gene as part of your genotype.


What is an organism that is heterozygous for a harmful trait?

Assuming the deleterious trait is recessive, the individual would be called a carrier.


Why can an individual be a carrier but not have that disorder?

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


If a dominant homozygous reproduced with a heterozygous could their offspring be recessive?

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!


Is a person who is homozygous recessive for a recessive genetic disese 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.


If one parent has beta thalassemia what are the chances the baby will inherit the condition?

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.

What is a person who has recessive allele for a trait but does not express that trait?

They would be considered a carrier. ------------------------------- More precisely a heterozygote. A carrier would imply that the recessive trait causes disease.
