Which genes are dominant and which are recessive?

Dominant genes are always expressed in preference to recessive genes in cased where both genes are present.


What genes are expressed even when present on only one chromosome?

dominant genes


Genes that prevent the other gene from showing traits are called?

Dominant genes. Dominant genes are always expressed in an organism's phenotype when present, masking the expression of recessive genes.


A gene that is not expressed when paired with a dominant allele is called?

A recessive gene. These genes are masked by dominant genes when they are present together in an individual's genetic makeup.


Why are some genes are called dominant?

What trait is is expressed when two diffrent genes for the same trait are present?

A dominant trait is expressed when two different genes for the same trait are present.


What trait is expressed when two different genes for the same trait are present?

dominant


What are the difference between dominant and recessive genes?

Dominant genes are always expressed in the phenotype, even if there is only one copy present. Recessive genes are only expressed if both copies are present. Dominant genes tend to mask the effects of recessive genes in the phenotype.


What trait is expressed when two different genes for the same trait are present is called?

This is called co-dominance - when both genes are expressed and visible in the phenotype.


The weaker of two genes is called what?

The weaker of two genes is called the recessive gene. In the presence of a dominant gene, the recessive gene is not expressed in the organism's phenotype.


What is it called when both dominant and recessive genes are present?

Heterozygous, I believe.


A trait which results from two dominant genes is called?

A trait resulting from two dominant genes is called codominance. This means that both genes are expressed in the offspring, leading to a phenotypic trait that displays characteristics of both dominant alleles.
