A dominant allele expresses itself in every offspring in every generation. A dominant allele expresses itself irrespective of the other allele present along with it.
A recessive allele, however is masked by the presence of dominant allele. It can express itself only if the other gene in the allele pair is also recessive. As a result, it is not expressed phenotypically in every generation.

∙ 11y agoThe dominant allele is the one that corresponds to the phenotype shown while the recessive allele is the one that corresponds to the alternate phenotype not shown by the organism. In pea plants (from Gregor Mendel's famous experiments), the "tall" allele was dominant over the "short" allele, so a pea plant with one or two "tall" alleles was a tall pea plant and a pea plant with two "short" alleles was a short pea plant.
In most animals, the genotype/phenotype link is much more complex - there are multiple alleles for some genes, some alleles show incomplete dominance or recessiveness, there are epigenetic influences, etc.

ex: AA, aa, BB, zz , ZZ, cc,.....etc.

Genes that are only seen when paired with a recessive gene?
if u have a recessive gene with a recessive gene then u can see the recessive gene but if you have a dominant gene with a recessive gene you can only see the dominant gene hope that helps:)
What is the different between dominant and recessive?
Dominant trait is the one which is expressed when the homologous pair of genes controlling it are either homozygous or Hetrozygous dominant; on the other hand recessive trait has both genes to be homozygous recessive. in fact trait is controlled by the form of genes. Dominant gene expresses even when it is in the company of recessive gene. However recessive gene expresses only when in company of recessive 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
Which form of gene pair is expressed when both dominant and recessive are present?
If the gene is governed by a dominant and recessive allele, then if the dominant allele is present, the dominant trait will be expressed. If both alleles are recessive, then the recessive trait will be expressed.
What gene won't display its trait in the prescience of a dominate trait?
The recessive form of a gene, called a recessive allele, will not be expressed in the presence of the dominant form of the gene, called a dominant allele.
Is a disorder know as a dominant or recessive?
Dominant disorders can be passed onto the offspring if the dominant gene is present in the offspring.
Genes that are only seen when paired with a recessive gene?
if u have a recessive gene with a recessive gene then u can see the recessive gene but if you have a dominant gene with a recessive gene you can only see the dominant gene hope that helps:)
What is an organism that has a dominant and a recessive copy of a gene?
dogs have a dominant and a recessive copy of a gene
A gene is recessive when?
Most genes have two copies of each gene with dominant gene "trumping" the recessive one. The gene is recessive because it is said not to do much of anything unless paired with another recessive gene, but if paired with a dominant gene, the dominant gene wins.
Is a situation in which a dominant allele completely masks a recessive allele for a gene.?
If you have 2 dominant alleles, the gene will be dominant, if you have 2 recessive alleles, the gene will be recessive. But if you have 1 recessive and 1 dominant, the Dominant allele will mask the recessive one.
How many copies of a recessive gene does it take to overpower a dominant gene?
It takes 8 copies of a recessive gene to overpeower dominant gene
Can a recessive gene be hidden from a dominant?
The dominant gene will always "cover up" the recessive gene, although there are instances of codominance, in which both phenotypes will be displayed, because one gene is not completely dominant over the other. There is also what is called 'incomplete dominance', when the actual phenotype is somewhere between the two.

Dominant trait is the one which is expressed when the homologous pair of genes controlling it are either homozygous or Hetrozygous dominant; on the other hand recessive trait has both genes to be homozygous recessive. in fact trait is controlled by the form of genes.

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 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
Which form of gene pair is expressed when both dominant and recessive are present?
If the gene is governed by a dominant and recessive allele, then if the dominant allele is present, the dominant trait will be expressed. If both alleles are recessive, then the recessive trait will be expressed.
What gene is masked if it is paired with a dominant gene?
The different forms of a gene are called alleles. In Mendelian genetics, a gene has a dominant allele and a recessive allele. The dominant allele masks the recessive allele if present. So there are two possible dominant genotypes: homozygous dominant, in which both dominant alleles are present; and heterozygous, in which one allele is dominant and the other allele is recessive. The only way to express a recessive trait is to have the homozygous recessive genotype.
