Alleles are neither entirely recessive nor entirely dominate. An allele is any one of a number of alternative forms of the same gene on a chromosome.
For example: say a flower only blooms either red or white flowers. There is a different allele for each color-- a red allele and a white allele. Now, one color may be dominate over the other recessive gene. For example, if the red color was dominate and the white color was recessive, then those certain alleles would be dominate and recessive, respectively. But alleles in general cannot be either recessive or dominate. It depends on the gene and it depends on the trait.

What can be dominant or recessive?
Alleles can be dominant or recessive
How are dominant and recessive alleles are represented in a punnet square?
Dominant alleles are shown by a capital letter and recessive alleles are lowercase letters.
How are Dominant and recessive alleles are represented in Punnet Square?
Dominant alleles are shown by a capital letter and recessive alleles are lowercase letters.
What is gene pair consists of two dominant alleles or two recessive alleles?
A gene pair that consists of 2 dominant or 2 recessive alleles is considered homozygous dominant or homozygous recessive.
What type of alleles mask recessive alleles?
Dominant alleles :-)
What are the two terms for having matching alleles for a certain trait?
The two terms for having matching alleles for a certain trait are "homozygous dominant" (two dominant alleles) and "homozygous recessive" (two recessive alleles).
How dominant and recessive alleles are represented in a Punnett Square?
Dominant alleles are written in upper case (i.e, 'A'), while recessive alleles are lower case (i.e, 'a')
How is recessive alleles different from dominant alleles?
You need two recessive alleles to get their trait, but only one dominant allele to get that trait. A dominant allele basically overrides a recessive one if they are together, but the recessive gene can show up in offspring.
How dominant and recessive are represented in a punnet square?
Dominant alleles are shown by a capital letter and recessive alleles are lowercase letters.
How do dominant alleles recessive alleles differs?
Dominant alleles are the ones that show up in the phenotype. Recessive alleles do not unless both alleles are recessive, but can be passed on. For example: Tt , T=tall and t=short. Tall is dominant and short is recessive. You are tall and can pass on the short gene. Or, you can use black hair being dominant over red. Or, brown eyes being dominant over blue. Dominant can be seen on you and recessive can't.
Are organisms with alleles BB recessive or dominant?
Organisms with alleles BB are considered homozygous dominant. This means that the dominant allele (B) is expressed in the phenotype. Dominant alleles mask the effects of recessive alleles in heterozygous individuals.
What makes a dominant alleles different from a recessive alleles?
A dominant alle masks the expression of the recessive trait in a heterozygous genotype, a recessive allele is the phenotpye expressed is the recessive trait.
