Dominance in genetics is not a black-and-white thing. An allele may be dominant to one rival allele, but recessive to another. Ultimately, it may depend on the degree of functionality of the protein encoded by the allele. For instance, one allele may code for a non-functional protein, or not code at all. In that case, it would be recessive to any competing allele that did code for a functioning protein.
Also, phenotypes are often the result of gene complexes - no single allele codes for a particular phenotypic trait, but many together do. The relationship between dominant and recessive alleles in such a complex may be equally complex: there may be degrees of expression along a sliding scale, or specific values for each dominance/recessiveness relation (eg. spots or no spots; green eyes, gray, brown or blue; curls or no curls, etc).

What else can I help you with?
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.
Which versions of genes are dominant over others in genetic inheritance?
In genetic inheritance, dominant genes are versions of genes that are expressed over recessive genes. Dominant genes mask the effects of recessive genes when they are present together in an individual's genetic makeup.
What do you call oransim that posssses two dominant or two recessive genes for a single trait?
Homozygous dominant for two dominant genes or homozygous recessive for two recessive genes.
How are dominant and recessive genes related?
Dominate them. Recessive alleles do not show in your phenotype unless you have two of the same recessive allele. But if you inherit one dominant and one recessive, it is the dominant that always shows in your phenotype.
Can recessive genes become dominant?
Recessive genes do not become dominant. Dominant genes mask the expression of recessive genes in the presence of both alleles. However, if a recessive gene is selected for over time through breeding, it can become more prevalent in a population.
Are polygenic genes dominant genes?
Polygenic genes are usually dominant genes.
Do dominant genes affect recessive genes?
The dominant genes take over, and then the recessive genes hide away
How do dominant and recessive genes work?
explain how dominant genes work
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.
How is codominance difference from dominant and recessive relationship?
Codominance is when 2 dominate genes appear in the phenotype of an organism. (some one else can tell you what dominate and recessive genes are)
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.
Which versions of genes are dominant over others in genetic inheritance?
In genetic inheritance, dominant genes are versions of genes that are expressed over recessive genes. Dominant genes mask the effects of recessive genes when they are present together in an individual's genetic makeup.
What do you call oransim that posssses two dominant or two recessive genes for a single trait?
Homozygous dominant for two dominant genes or homozygous recessive for two recessive genes.
Are the fathers genes always the dominant genes?
No, the father's genes are not always dominant. Inheritance patterns can vary depending on the specific genes and traits being considered. Some traits may be dominant if they are expressed over recessive genes, while other traits may exhibit co-dominance or incomplete dominance.
What will happen if an organism has the dominant gene?
Dominant genes express themselves, phenotype depends upon genes .
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.
What are capital genes?
capital genes are dominant genes as they are written by capital letters
