Very often lower case letters are used to show recessive traits, and upper case for dominant, but this is not universal. Also, most traits aren't dependent on only one gene or "on/off" switch, but are rather part of a spectrum.

for example.
the dominant trait is symbolized by 'B'
the recessive trait would be 'b'

What stands for dominant allele?
Normally a dominant allele is represented by a capital letter. It can be any letter used. Example; Brown hair is dominant and blond is recessive. B represents the dominant allele (brown) and b represents the recessive (blond) in Bb. You can have any combination of two alleles; BB, Bb, or bb. BB would have brown hair, Bb would have brown hair or a mix, and bb would have blond hair. Instead of B we could have used T or any other letter.
What is allele masked by the dominant allele?
The Allele That Is Covered By The Dominant Allele Is The Recessive Allele.
What phenotype is produced by AB genotype?
The genotype AA represents a homozygous dominant genotype. The capital letter "A" represents the dominant allele, while the lowercase letter "a" would represent the recessive allele. If both dominant alleles are present in a genotype (homozygous dominant) then the phenotype is "A" phenotype. If one dominant allele and one recessive allele are present (heterozygous dominant) then the phenotype is "A". Finally, if both recessive alleles "a" are present (homozygous recessive) then the phenotype is "a". Therefore, the answer to your question is the genotype AA would result in an "A" phenotype because the genotype is homozygous dominant.
What symbol represents the recessive allele for pod color?
The recessive pod color is green and the symbol appears to be a pea pod.
What does a lower case letter of an allele refer mean?
A lower case lettered allele means that the allele is recessive.
A recessive allele is respresented by?
a lower case letter that is the same letter as the upper case letter that represents the dominant allele

How do you write dominant and recessive allels?
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!
What phenotype is produced by AB genotype?
The genotype AA represents a homozygous dominant genotype. The capital letter "A" represents the dominant allele, while the lowercase letter "a" would represent the recessive allele. If both dominant alleles are present in a genotype (homozygous dominant) then the phenotype is "A" phenotype.

Finally, if both recessive alleles "a" are present (homozygous recessive) then the phenotype is "a".

In a punnet square a small letter stands for what type of allele?
A small letter stands for a recessive allele.
What is the probability that a offspring will have wrinkled seeds?
R represents the dominant round allele, and rrepresents the recessive wrinkled allele. :D
What symbol represents the recessive allele for pod color?
The recessive pod color is green and the symbol appears to be a pea pod.
What is a recessive genes?
Recessive is a relative term used to describe the relationship to another allele termed the dominant allele. That traits of the recessive allele will only be shown if the person has two copies of the recessive allele. If a dominant allele is present, then the recessive trait will not be shown.
How do you use dominant allele in a sentence'?
The dominant allele overpowers a recessive allele, therefore when the two are combined (heterozygous) the phenotype of the organism becomes whatever the dominant allele represents.
What does a lower case letter of an allele refer mean?
A lower case lettered allele means that the allele is recessive.
Is albinism controlled by a dominant allele or by a recessive allele?
Recessive allele.
