A non-example of a dominant gene would be a recessive gene, which only expresses its trait when two copies are present (one from each parent). For instance, if the gene for blue eyes is recessive, a person would need to inherit the blue eye gene from both parents to express that trait. In contrast, a dominant gene, such as one for brown eyes, would be expressed even if only one copy is inherited.

How does dominance apply to heredity?
If some gene is dominant it will always be more hereditary than a non-dominant gene. Like brown eyes, the brown eye gene is dominant so a couple with blue and brown eyes will have a child with brown eyes no matter what.
What is recessive gene and dominant gene?
A dominant gene is always expressed if present, and the recessive gene is only expressed with the homozygous recessive genotype. For example, if the dominant gene is red (represented by the letter R) and the recessive gene is white (represented by the letter r), then a homozygous dominant organism's genotype will be RR, and its phenotype will be red. If the organism is homozygous recessive, then the genotype will be rr and the phenotype will be white. If the organism is heterozygous, then the genotype will be Rr, and the organism will be red.
What is organisms with 1 dominant and 1 recessive gene?
An organism with one dominant and one recessive gene for a particular trait is said to be heterozygous for that trait. The dominant gene will typically mask the expression of the recessive gene, resulting in the dominant phenotype being expressed. For example, if "A" represents a dominant allele and "a" represents a recessive allele, the heterozygous genotype "Aa" will display the trait associated with "A."
When one gene expresses itself over another the former gene is said to be the DNA?
The gene that expresses itself over the other is Dominant. The former gene is recessive.
What is meant by dominat and ressesivegene give an exampleof each?
A dominant gene refers to a gene that is expressed over another gene in the same position on a chromosome. It will always show its trait in the individual's phenotype if it is present in their genotype. For example, if a person inherits a dominant gene for brown eyes, they will have brown eyes regardless of whether they also have a recessive gene for blue eyes. On the other hand, a recessive gene refers to a gene that is not expressed when there is a dominant gene present. It is only expressed in the phenotype when there are two copies of the recessive gene in the genotype. An example is the gene for blue eyes, which will only be expressed when an individual has two copies of the recessive gene and no dominant gene for brown eyes.
What is an example of dominant inheritance?
Dominant Inheritance is when one parent has a dominant gene and the other has a recessive gene. The dominant gene overpowers the recessive gene, and only the dominant gene is phenotypically expressed.Source: http://www.accessexcellence.org/RC/VL/GG/recessive.phpSome examples are variegate porphyria, Huntington's disease and myotonic dystrophy.source: http://genome.wellcome.ac.uk/doc_WTD020849.html
How do you spell recesive?
The correct spelling is recessive (refers to non-dominant gene).
What is a dominant gene and what is a recessive gene?
Recessive gene is one which is supressed and do not show their characteristics and dominant gene is one which show their characteristics for example if a father has brown hair and mother has black hairs and if their son has black hair then in this case gene which has characteristics of black is dominant and the other which has characteristics of brown colour is recessive
How does dominance apply to heredity?
If some gene is dominant it will always be more hereditary than a non-dominant gene. Like brown eyes, the brown eye gene is dominant so a couple with blue and brown eyes will have a child with brown eyes no matter what.
What does non dominant group mean?
A non-dominant group is the group with less power.. For example women are non-dominant, men are dominant, heterosexuals are dominant, gays are non-dominant. The group that sets the polices, laws and "standards" OS dominant. The group with power is the dominant group.
Is a tufted head on a duck a dominant gene or a resesive?
The tufted head trait in ducks is typically a dominant gene. This means that if a duck carries the tufted head gene, it is likely to express the trait, even if it also carries a recessive gene for a non-tufted head.
What is recessive gene and dominant gene?
A dominant gene is always expressed if present, and the recessive gene is only expressed with the homozygous recessive genotype. For example, if the dominant gene is red (represented by the letter R) and the recessive gene is white (represented by the letter r), then a homozygous dominant organism's genotype will be RR, and its phenotype will be red. If the organism is homozygous recessive, then the genotype will be rr and the phenotype will be white. If the organism is heterozygous, then the genotype will be Rr, and the organism will be red.
When one gene expresses itself over another the former gene is said to be the DNA?
The gene that expresses itself over the other is Dominant. The former gene is recessive.
What is meant by dominat and ressesivegene give an exampleof each?
A dominant gene refers to a gene that is expressed over another gene in the same position on a chromosome. It will always show its trait in the individual's phenotype if it is present in their genotype. For example, if a person inherits a dominant gene for brown eyes, they will have brown eyes regardless of whether they also have a recessive gene for blue eyes. On the other hand, a recessive gene refers to a gene that is not expressed when there is a dominant gene present. It is only expressed in the phenotype when there are two copies of the recessive gene in the genotype. An example is the gene for blue eyes, which will only be expressed when an individual has two copies of the recessive gene and no dominant gene for brown eyes.
What gene will exhibit its traits even in a prensesce of a recessive gene?
A dominant gene will exhibit its traits even in the presence of a recessive gene. This is because the dominant gene masks the expression of the recessive gene when present in the same individual.
Dominant gene plus Dominant gene?
It would be definite that you have that gene or trait.
What is it called when a ressesive and dominat gene mix?
When a recessive and dominant gene mix, the dominant gene will typically determine the trait expressed in the offspring. This is known as dominant inheritance, where the dominant gene masks the presence of the recessive gene in determining the phenotype.
