ACCORDING TO GREGOR MENDEL'S LAW OF DOMINANCE:- Dominant Allele refers to the expressed trait in a pair of genes,while the dormant,suppressed trait is the recessive allele.
Alleles carry the sequence of DNA for a particular form of a gene, such as a dominant or recessive trait.
The word dominant means most important, powerful, or influential. The word recessive means relating to or denoting heritable characteristics.

Pure dominant = two dominant genes that make a "pure dominant" trait. Pure Recessive = two recessive genes that make a "pure recessive" trait.
There is dominant and there is recessive. There is no dominant recessive. A dominant gene will always be expressed when present, such as in the homozygous dominant genotype (RR), or heterozygous genotype (Rr). A recessive allele is only expressed when the genotype is homozygous recessive (rr).
I am pretty sure the recessive and dominant alleles you are talking about are covered in Biology. Recessive alleles are basically alleles that are received from both parent's DNA that are carries, (dd). However, dominant alleles are (exactly what it says) always expressed. If there is one dominant allele and one recessive allele the dominant allele overpowers the recessive. (DD) and (Dd)overpowers (dd).
Dominant in science means either 'expressed' in genetic terms or 'widely held and accepted as the basis of comparison' in general terms such as "the dominant view".

Dominant and Recessive
Alleles can be dominant or recessive

normally, the dominant allele is expressed as a capital letter and the recessive allele is expressed as a lowercase letter, if that's what you mean!
is malignant melanoma dominant or recessive
No, I think you have your terms confused.The terms "dominant" and "recessive" are applied to alleles of a genotype. A genotype is an expression (using upper- and lower-case letters) that shows what alleles an organism has for a particular locus. The two alleles (in most cases) inherited (one from mother and one from father) can either be dominant or recessive. The recessive allele is not fully expressed in the presence of the dominant allele and is only expressed when there are two recessive alleles. The genotype could be called "recessive" I suppose if the genotype is homozygous recessive. But remember that two recessive alleles as a genotype is only one possibility - in which case you can't say the "genotype is recessive".The phenotype is dependent on the genotype. If present, the dominant alleles (in simple Mendelian genetics) will determine the phenotype - what the organism's trait or characteristic is. The phenotype will never be what is coded by the recessive allele unless the genotype is two recessive alleles.
Dominant in science means either 'expressed' in genetic terms or 'widely held and accepted as the basis of comparison' in general terms such as "the dominant view".
Dominant traits are the traits that mask the recessive traits. The dominant traits are stronger than recessive!
The dominant overpowers the recessive traits. The dominant trait is the trait the the offspring will most likely have.
