Codominance. It's the case of AB blood types, for instance. Neither trait is dominant over the other, so both manifest.

What is it called when two forms of a trait are both dominant at the same time?

Codominance. It's the case of AB blood types, for instance. Neither trait is dominant over the other, so both manifest.


What is a trait that is expressed even if only one gene for that form of the trait is inherited?

It is a dominant trait. You only need one gene of a dominant trait for that trait to be expressed. You need two copies of the recessive trait in order for the trait to be expressed.


When a trait is not expressed when paired with a dominant allele is the definiton of?

The trait that is not expressed when paired with a dominant allele is known as a recessive trait. It is masked by the dominant trait in individuals carrying both alleles.


A dominant phenotype will only be expressed if the individual is homozygous dominant for that trait?

Well actually not necessarily. An individual can be homozygous or heterozygous dominant for a trait. As long as they have that dominant allele in that specific genetic trait, they will automatically express the dominant phenotype. If a person is homozygous dominant, it just means that they will pass on both dominant traits to the offspring. If a person is heterozygous dominant , it means that they will pass on both a dominant and recessive trait to their offspring.Hope that helps ! =D


What is trait called that appear only when both alleles are present?

A trait that appears only when both alleles are present is called a recessive trait. In this case, the trait is masked when the dominant allele is present, but becomes visible when two copies of the recessive allele are inherited.

What is a trait that masks a trait called?

A trait that masks another trait is called a dominant trait. This means that when an organism carries both dominant and recessive alleles for a particular gene, only the dominant trait will be expressed in the phenotype.


A trait which results from two dominant genes is called?

It would depend on if the dominant genes are the same or different. Say the dominant alleles were different. In this case, they are co-dominant. If they are the same and both dominant homosytus.
