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).

∙ 12y agodominant genes, because the dominant gene is the gene that can be seen, but the recessive gene is the one that can not be seen.

The most powerful genes are said to be?
Dominant, as in dominant and recessive (weaker) genes.
Are freckles dominant recessive or dominant dominant?
dominant genes for freckles
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.
What is the difference between homzyguos and heterozyous?
Homozygous recessive: is when the genes are both recessive Homozygous dominant: is when the genes are both dominant (traits show) Heterozygous dominant: is when one gene is dominant and one is recessive (traits show) Heterozygous recessive: is the same as heterozygous dominant but the dominant genes are inactive
Recessive genes will always be masked by dominant genes This is Mendel's principle of?
Dominance
Are polygenic genes dominant genes?
Polygenic genes are usually dominant genes.
Are the fathers genes always the dominant genes?
No - the father's genes are not always the 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.
The most powerful genes are said to be?
Dominant, as in dominant and recessive (weaker) genes.
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)
Are freckles dominant recessive or dominant dominant?
dominant genes for freckles
What will happen if an organism has the dominant gene?
Dominant genes express themselves, phenotype depends upon 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.
What is the difference between homzyguos and heterozyous?
Homozygous recessive: is when the genes are both recessive Homozygous dominant: is when the genes are both dominant (traits show) Heterozygous dominant: is when one gene is dominant and one is recessive (traits show) Heterozygous recessive: is the same as heterozygous dominant but the dominant genes are inactive
What are capital genes?
capital genes are dominant genes as they are written by capital letters
