How is a dominant trait represented in a punnett square?
Dominant alleles are written in upper case (i.e, 'A'), while recessive alleles are lower case (i.e, 'a')
What following genotypes will express a dominant trait?
For a dominant trait to be expressed, you either need a RR or an Rr genotype. The other genotype, rr, is recessive only. In genetics, capital letters represent a dominant allele, and lower case letters represent the recessive allele.
A recessive allele is represented by an letter?
Most of the time a recessive allele is expressed using lower case letters in comparision to the upper case dominant alleles.
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.
In the pair Tt the capital T represents what gene?
I'm not 100% sure what you're talking about here, but this looks like alleles, not genes. For every gene, there is one copy on each of a pair of chromosomes. The gene can take different forms, called alleles. In the "simple" case, there are only two possible alleles - dominant and recessive. When geneticists are analyzing the probability that an offspring will have the trait in question, they use a capital letter to indicate the dominant allele and a lower-case letter to indicate the recessive allele. The letter used is usually somehow representative of the trait. For Example, T (whether upper or lower case) might refer to a gene that has something to do with tongue. But there is no standard set of letters used to designate specific genes in this context. The T and t in this case could represent any gene, though the T clearly represents the dominant allele and the t represents the recessive allele.By the way, in a simple, one-gene, dominant/recessive case an individual with one Dominant and one Recessive gene (Tt genotype) would have the trait in question, because the dominant allele overrides the recessive one. Only a person with a tt genotype would lack the trait.
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
What stands for recess?
a recessive allele is shown using a lower case letter a dominant allele is shown using a capital letter
Is the lower case letter in a punnet square a ressesive allele?
By convention yes.
What is the general term for an allele that masked in the phenotype by the present of another allele?
Recessive. It is denoted by the lower case version of the first letter of the Dominant gene. For example, if the dominant is "A" then the allele is "a".

What letter is a dominant allele represented with?
When writing a genotype, it is classic in genetics to use upper case letters to indicate dominant alleles and lower case letters to indicate recessive alleles. Let's say the flamingo color gene is represented by the letter P. The pink allele is dominant, so it would get a capital P, but the purple allele is recessive, so it would get a lowercase p.
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.
What is the genotype of a flower that is homozygous recessive?
lower case letter and lower case letter Example:ff
