A dominant genotype is represented as DD or Dd but with many different letters. The DD is a homozygous dominant, while the Dd is the heterozygous dominant. Recessive is always represented as dd or rr or whatever letter you want to use. It is always homozygous recessive. There can never be a heterozygous recessive.

How is a recessive allele from a dominant allele?
its different because adominant allele is in charge
What is dominant chromosome?
A dominant chromosome refers to a chromosome that carries a dominant allele, which expresses its trait even when paired with a recessive allele. In genetics, dominant alleles can mask the effects of recessive alleles in a heterozygous organism. This means that if an individual has one dominant allele for a trait, that trait will be expressed, regardless of the presence of a recessive allele. Dominance is a key concept in Mendelian genetics, influencing inheritance patterns.
Which traits oberved were dominant and recessive?
In genetics, dominant traits are those that are expressed when an individual has one or two copies of the dominant allele, while recessive traits are only expressed when an individual has two copies of the recessive allele and no dominant allele present. Dominant traits often mask recessive traits in heterozygous individuals.
When working out a genetics problem how does one represent a recessive gene?
In genetics problems, a recessive gene is typically represented by a lowercase letter, such as "a," while the dominant allele is represented by an uppercase letter, like "A." This notation helps distinguish between the two alleles and indicates that the recessive trait will only be expressed phenotypically when an individual carries two copies of the recessive allele (aa). In contrast, individuals with at least one dominant allele (AA or Aa) will display the dominant trait.
What is the type of trait that can be masked?
The type of trait that can be masked is known as a recessive trait. In genetics, recessive traits require two copies of the recessive allele (one from each parent) to be expressed phenotypically, while a dominant allele can overshadow or mask the expression of the recessive allele. As a result, individuals with one dominant and one recessive allele will display the dominant trait, concealing the presence of the recessive trait.
What does the word dominant mean in genetics?
In genetics, "dominant" refers to an allele that will be expressed in the phenotype if present, masking the expression of the corresponding recessive allele. This means that even if an individual has one dominant allele and one recessive allele for a particular trait, the dominant allele's phenotype will be visible.

What is dominant chromosome?

This means that if an individual has one dominant allele for a trait, that trait will be expressed, regardless of the presence of a recessive allele. Dominance is a key concept in Mendelian genetics, influencing inheritance patterns.
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.
Which traits oberved were dominant and recessive?
In genetics, dominant traits are those that are expressed when an individual has one or two copies of the dominant allele, while recessive traits are only expressed when an individual has two copies of the recessive allele and no dominant allele present. Dominant traits often mask recessive traits in heterozygous individuals.
What is allele masked by the dominant allele?
An allele that is masked by the dominant allele is called a recessive allele. When an individual has one dominant allele and one recessive allele, only the trait determined by the dominant allele will be expressed. The recessive allele will only be expressed if an individual has two copies of it (homozygous recessive).

In contrast, individuals with at least one dominant allele (AA or Aa) will display the dominant trait.
What does a capital letter show about a gene?
A capital letter in genetics typically represents the dominant allele of a gene. This means that the trait associated with that allele will be expressed in an individual, even if they have only one copy of the dominant allele. Lowercase letters are used to represent recessive alleles, which will only be expressed if an individual has two copies of the recessive allele.
An allele that is hidden by other alleles is called?
i think the answer your lokking for is recessive Recessive is when you have a trait in your genome but it doesn't show in your physical appearance
In one allele is dominant to a recessive allele?
In a dominant-recessive allele relationship, the dominant allele will be expressed phenotypically over the recessive allele. This means that even if an organism carries one dominant and one recessive allele for a particular trait, the dominant allele will determine the observable characteristic.
What is the type of trait that can be masked?
The type of trait that can be masked is known as a recessive trait. In genetics, recessive traits require two copies of the recessive allele (one from each parent) to be expressed phenotypically, while a dominant allele can overshadow or mask the expression of the recessive allele. As a result, individuals with one dominant and one recessive allele will display the dominant trait, concealing the presence of the recessive trait.
What letters are given in genetics to represent the dominate allele?
capital letters, such as PP equals two dominant alleles, pp equals two recessive alleles.
